The other problem that sometimes occurred was that I've tended to live with people with whom I have a lot of mutual friends, and there's always possibilities for hurt with who does or doesn't invite who to do stuff. I lived for a bit with a few people with whom we had a mutual "friend" who didn't like me much and on several occasions invited everyone else in the house over for a party, except me. Nice. (And these were big parties, not select dinner parties or whatever.) There was no particular reason for her to not like me - I wasn't the only person I knew who had that experience - she just had people she liked on one list, and people she didn't on another list, there didn't seem to be much logic to it.
EDIT: Despite the above, I would consider living with people again. But I'm a bit apprehensive about it. There was too much coming and going when I had flatmates and I ended up feeling very disrupted and unsettled. It's annoying when people you're not even in a relationship with, or bst friends with, can have that much effect on your life.
