I do have rules, and etiquette things. I think it's a southern thing too, to an extent. I'll hold the door for someone, but if they don't say, "Thank you," it pisses me off. I say, "Yes, ma'am," and, "Yes, sir." Stuff that is maybe archaic in a lot of ways, but that's how I was raised, and I don't think there's really any harm in that.
