My awkward moment of the day

So Alexa (Bio Prof) is grading my draft of my report in lab today. We leave to go collect stuff, I come back, and she says "Hey Wren? I have a question."

I assume she wants to know why I did X dumb thing in my draft, so I whine "Whaaat?"

"Why do people get their tongues pierced?"
"... .... ...It depends on the person. I got mine done because I thought it would look cute, and I wanted to get a body piercing that wouldn't leave a visible scar when I decided I didn't want it anymore."
"So why do other people get it done?"
Oh, shit. Well, why not? "Supposedly it makes oral sex feel better."
Alexa, without even blinking, turns to the TA (Claire) and says "You let me ask her that. You KNEW, didn't you!"
