# If the room is empty, and you're leaving, turn off the lights. Please.

# Take off your hat indoors.

# Don't destroy or abuse property. Particularly not if it belongs to somebody else.

# Say "excuse me" rather than just pushing past people in a crowd or a constricted space.

# When in class or in the library, put your cell phone on vibrate. PLEASE.

# If you yak or see someone yak in a place that's a bit out of the way--a basement, far-off corner, or anywhere that isn't a toilet, really--make your best effort to tell someone responsible that there's a stinky, biohazardous mess on the floor.
