Mind your I's and U's

Don't drink too much if you want to date her again.

Don't wake roommates when you come in late from a date to regale them with accounts of the good time you had. And don't throw your clothes all around the room while undressing.

Don't collect pins. Though wearing a boy's fraternity pin does not signify formal engagement on Indiana campus, it is considered very bad taste to wear more than one at a time.

Don't smoke where ashtrays are not provided.

Don't "periscope" (peek) over a fellow student's shoulder, whether you are cribbing or just checking up on progress.
