Oh, but how could I forget this?
My Research Methods class has 9 students in it, including myself. At one point, the instructor said "everyone please exchange your phone number with another person in the class, in case you ever miss class, so you can exchange notes."
I waited one second too long, and everyone was suddenly all paired up. Cue the "EFF EFF EFF!" going through my head. Panic set in.
The teacher then had to be like "Uh. Will someone please give Sarah their phone number?" NO ONE DID. So she finally had to just pick someone out.
Omg. So embarassing.
