From the mouths of babes.

I recently had an overnight stay with my grandkids, which means snacks, negotiations, mysterious crumbs, very little personal space, and at least one conversation that unexpectedly becomes a life lesson.

We ordered pizza.

As I picked up a slice, my five-year-old grandson looked at me with genuine concern and said, “Grandma, you can’t eat that. It has cheese.”

He knows I’m lactose intolerant. In his wonderfully logical five-year-old mind, lactose intolerance means dairy is forbidden. Cheese equals dairy. Therefore, Grandma plus pizza equals impending disaster.

I explained that I could eat a small amount of cheese without getting a tummy ache.

Naturally, this did not satisfy him.

He wanted to know why. How could I be lactose intolerant but still eat cheese? Was I intolerant or wasn’t I? Apparently, Grandma’s digestive system was now under a full investigation.

I told him that my body can tolerate a certain amount of lactose. Sour cream, yogurt, cream cheese, cheese balls, small amounts of aged cheese—I can generally eat them as long as the serving keeps me below my personal threshold of about four grams of lactose.

But if I eat too much?

My body lets me know.

Immediately.

With enthusiasm.

There is no misunderstanding the memo.

That started a conversation about what it means to tolerate something. We talked about how everyone has different limits. One person’s body may be comfortable with an amount that causes someone else’s body to launch a full-scale protest.

Then came the more interesting question:

If you can tolerate a little, should you keep increasing the amount you tolerate?

No.

Not if doing so causes you pain, stress, or an upset stomach.

And there it was, sitting between the pizza box and a curious five-year-old: a lesson that had very little to do with cheese.

Just Because You Can Tolerate It Doesn’t Mean You Should

We tend to treat tolerance as a virtue.

We praise people for being able to handle pressure, inconvenience, difficult personalities, unreasonable expectations, long hours, poor sleep, constant interruptions, and everyone else’s emotional luggage.

“She can handle it.”

“He never complains.”

“She’s so strong.”

Sometimes strength is knowing that you can tolerate something.

But wisdom is knowing when tolerating it is costing you too much.

There are plenty of things we technically can tolerate:

• The friend who only calls when she needs something.
• The family member who makes little comments and then says, “I was only joking.”
• The client who ignores every boundary because we answered “just this once.”
• The schedule with no room to breathe.
• The job that expects us to be available every waking hour.
• The habit of saying yes while our entire body is screaming no.
• The relationships in which we keep swallowing our feelings to avoid upsetting someone else.

We can tolerate all kinds of things.

Until we can’t.

The trouble is that most of us don’t choose a healthy level of tolerance and stay there. We slowly increase it.

We answer one work email during dinner. Then three. Eventually, we’re carrying our phone from room to room like it has been appointed head of the household.

We agree to help one time. Then it becomes expected.

We excuse one disrespectful comment. Then we start bracing ourselves before every interaction.

We skip one walk, one meal, or one night of decent sleep because someone else needs us. Soon, caring for ourselves feels like one more chore we don’t have time to do.

Every small increase seems manageable.

Until our body sends the memo.

Your Body Keeps Better Records Than You Do

Your body notices what your mind keeps trying to explain away.

It notices the clenched jaw.

The shallow breathing.

The tight shoulders.

The racing thoughts at two in the morning.

The fatigue that doesn’t disappear after a full night’s sleep.

The headaches, cravings, digestive problems, irritability, and blood glucose that seems determined to write its own dramatic storyline.

Stress is not only an uncomfortable feeling. It creates a physical response. Your brain interprets a threat—whether that threat is a charging bear or another message from someone who drains the life out of you—and your body prepares to protect you.

Stress hormones rise. Your heart rate may increase. Your muscles tighten. Your liver releases stored glucose so you have energy available to respond.

That system is incredibly useful when you need to run from danger.

It is less useful when the “danger” is a life built around constantly tolerating what does not support you.

For women living with type 2 diabetes, boundaries are not simply a relationship skill or a trendy form of self-care. They can be part of protecting our health.

That does not mean every stressful interaction causes a glucose crisis. It means that chronic, repeated stress matters. The body does not neatly separate emotional pressure from physical health just because we would prefer it to.

Your nervous system is not interested in whether you had a “good reason” for overextending yourself.

It only knows that it keeps being asked to respond.

A Boundary Is Not a Punishment

Many people hear the word boundary and imagine confrontation, rejection, or a dramatic speech delivered while storming out of the room.

Most boundaries are much quieter than that.

A boundary can sound like:

“I’m not available tonight.”

“I need time to think about that.”

“I can help for an hour.”

“I’m going to rest before I decide.”

“I don’t discuss my weight or food choices at the dinner table.”

“I care about you, but I cannot take responsibility for this.”

“No.”

Yes, “no” is a complete sentence, although some people will request the extended director’s cut.

A boundary is not about controlling what someone else does. It is deciding what you will participate in, accept, or continue carrying.

It is not: “You must stop behaving that way.”

It is: “If this continues, here is what I will do to care for myself.”

Boundaries are not proof that we love someone less.

Sometimes they are proof that we have finally included ourselves among the people deserving our care.

Find Your Threshold Before Your Body Finds It for You

My lactose threshold is fairly clear. I can eat a small amount, enjoy my pizza, and continue having a lovely evening with my grandkids.

If I decide that tolerating a little means I should prove I can tolerate a lot, the evening may take a turn.

Our emotional and physical boundaries deserve the same attention.

What can you participate in without abandoning yourself?

What can you give without resentment?

What can you handle without paying for it with your sleep, peace, energy, or health?

Where have you slowly increased your tolerance for something that does not feel good simply because you can endure it?

You do not need to wait until something becomes unbearable before setting a boundary.

Pain is not the entrance fee for permission to change.

The goal is not to become intolerant of every inconvenience or uncomfortable feeling. Growth occasionally requires discomfort. Relationships require flexibility. Life will not arrange itself around our preferences—and children certainly will not.

The goal is to notice the difference between discomfort that helps you grow and repeated distress that teaches you to disappear.

A small amount of tolerance may allow us to live fully, love people generously, and enjoy a slice of pizza with our grandkids.

Too much tolerance can leave us physically uncomfortable, emotionally depleted, and wondering why everyone keeps asking more of us.

Sometimes the healthiest thing we can say is not, “I can’t handle this.”

It is:

“I probably could tolerate more—but it would cost me too much.”

That is not weakness.

That is awareness.

And occasionally, it is also how Grandma gets to eat the pizza without getting a tummy ache.
