Whoever blinks first in a staring contest loses. A lot of drama works exactly the same way.

Some conflicts are not really about the disagreement; they are about who reacts first. The other person is waiting for you to raise your voice or send the paragraph, because that turns the story into one about you. Staying steady is not weakness, it is refusing to hand over the thing they came for.

When something is built to get a rise out of you, give it nothing for one full day. Read it, put the phone away, do something with your hands. If it still matters tomorrow, answer then, calm and on your own schedule.
