It's probably just me being antisocial. I have some friends who repeatedly "drop in" with no prior warning. I'm not particularly house proud and they wouldn't judge me for the house being less than showhome standards anyway. But I really don't like it when they call in and then end up staying for an hour and a half chatting and eating all my biscuits with the assumption that if I'm home, it's ok for them to do so. I don't feel it's ok to not let them in. I'm not really looking for solutions, just wondering if I'm being grumpy and antisocial.
