I put on a morph suit and ran around to scare people. Only problem is I've done it before halloween with friends and the RAs don't like it so as soon as I appeared they told me that wearing a mask is "against school policy" and that if she caught me wearing it on campus again I'd get in a lot of trouble.
There's no specific policy saying I can't wear a mask but they could probably peg me for a few "policies" because of their vagueness. Of course I put it back on once I left the building but the threat kinda ruined the mood so I took it off after a while
