From last night

My friends leave for the bathroom, and I am left alone with her at the bar.

“I majored in math, with a concentration mostly in triangles.” She has a large purple triangle suspended above her on a spring from her headband, like a Teletubby.

“Hah, Pythagorean Theorem, am I right?” I offer nervously, trying to make conversation.

She looks at me with menace.

“It’s just not like that at all.”

“I majored in squaaaaaares,” I say, cracking up.

A sterner look, and silence. My friends do not return.
