I have 3 keys for our apartment (one for the brownstone, one for the foyer, one for the apartment door), a mail key, and 3 old keys that I never use. I think they are for work and I should really take them off my key chain, but maybe one day I will be kidnapped and locked in a room and one of those keys will open the door.
Hmm writing that out, that seems like the world's dumbest reason for keeping keys on a keychain. I'll get rid of them later today.
Anyway, how many keys are on your key chain?
