At my parents’ 30th anniversary dinner, I arrived dressed in a suit and tie—only to discover that my seat had been given to my sister’s new boyfriend. When I asked where I was supposed to sit, Mom simply said, “You didn’t bring a plus-one, so just stand for now.”

She returned a food container I had lent her weeks earlier, then walked inside holding a Frappuccino as though nothing had happened.

“So,” she said, “are you done being dramatic?”

I stared at her.

“You think I’m the one being dramatic?”
