I don't take my shoes off in other people's houses unless I'm going to be there for a while and am comfortable.
I don't take my shoes off in my house if I know I'm going to have to put them right back on again and they're tennis shoes.
It feels weird to have shoes on in the house xD
I love going barefootonly thing is at my campus I have to walk past a couple of frat houses and so it's like no-mans zone for glass there -.- luckily it just rained a ton so the upper sidewalks are clean, but the lower ones are nasty -.-
