People who wear their shoes into my house piss me off so fucking much. I HATE IT. If you are going to come into my house, you take your fucking shoes off or you wait outside.
It is definitely a northern thing. All my canadian friends always take their shoes off. My old roommate never took her shoes off and drove me crazy on a daily basis. My friends from southern california never take their shoes off either. I hate it so, so much.
Even if there isn't as much mud or whatever in the south, you still walk through disgustingness all the time. You still walk through sticky bars with spilled alcohol and get gum on your shoes or step in dog shit. It's not like you look at the bottom of your shoes every time you walk into a house. TAKE THEM OFF!
