You’re talking about something else when they say it.
“You always do that when you’re nervous.”
You look at them.
“Do what?”
They tell you.
It’s something small. Something you hadn’t realized anyone could see.
You laugh.
“I’m not nervous.”
They don’t argue. They just smile and keep talking.
But you’re not really listening anymore.
You’re thinking about all the other times you’ve done it.
How long they’ve noticed.
Who else has noticed.
For the rest of the conversation, you make sure you don’t do it again.
