Glok, I'd come over if you invited me
I love knowing I'm not alone with this-- and it's interesting how many different reasons we all have for the same kind of behavior.
I always feel weird when I tell people that they can't come over because it's too messy. I'm driving a neat freak friend today in my messy car and stressed about that.
I think there is also some stress about just having people in my space. I have a couple of friends that won't leave unless I directly ask them to. Entertaining outside the house is so much easier, especially in separate cars!!!!
