Hangover.

The most accurate word you'd use to describe how you're feeling right now.

Last night was... something. You should've known not to let your friends drag you to the damn party the night before classes. You remember drinking. So much drinking. And dancing, and--

"Attention everyone! We have a new student, joining our major today. Please welcome her warmly."

You freeze. You notice a familiar face walking through the door, greeting the professor with a smile on her face.

It's the girl from last night's party with whom you had a really intense make out. You hide your head, pretending to work on your MacBook, sitting on your usual seat.
