So I decided he's going to be campus security and takes his job way too seriously. He will gladly break up parties or fights because it brings him joy to watch all you young people get sad while drunk.

Also totally confiscating booze if he sees any. For...reasons.

Of the not drinking it myself variety why would you say that.

He doesn't like the Physics or Engineering professors because he always has to call the fire department, or actual police, or an ambulance on them for various reasons.

Like when a girl's pinky got severed, gross.

Also might be an alumni of the school. Talk about awkward.
