you were walking around campus when you saw a half-human half-wolf hybrid yelling at the vending machine.. it looked like his juice had gotten stuck in there which would explain why he's yelling at it like some child who didn't get their way.

"GIVE ME MY DRINK DAMMIT!!!!"

He yelled while he started to kick the vending machine over and over again his ear were flat on his head while his tail started to sway in a aggressive manner.. he looked very frustrated over that. Maybe you should help
