i don't think i've ever been afraid of being home alone but i've taken to investigating noises i haven't heard before with a pipe
not like a weapon, but in case it's something that's ajar or it's a forgetin bug or something i can just smack it with the pipe instead of having to get my hands dirty, go ALL the way to the bathroom, THEN continue doing what i was doing
though that said if it's like, a burglar, i could probably crack him over the head with it, run off, get a BETTER weapon (or just call the cops) and then come back
