A new label has been added: Living situations. I think that where you live and with whom is important in terms of relationships, but unless those relationships are romantic (ie, how to combine your home decor with that of your spouse), living situations are rarely talked about past college roommate issues. So guess what I'm going to do? Yep, that's right, talk about them.
Up until last month, I lived with my 2 cats in a large (although decrepit and overpriced) studio apartment here in San Francisco. Then, the cats and I moved to a house on the other side of town. We now live with two people, a dog, and another cat. The reason for this move was mostly financial-- my rent is now a little more than half of what it was before. But I was also often lonely living by myself, and I thought living with other folks would be a nice change. It turns out that may or may not be true. Like many people in San Francisco, my housemates are from Craigslist, people who were complete strangers before I answered their ad seeking a housemate. I don't know if this is a common thing in your area, but here, it's not relegated to just the young and poor (although I happen to be both). Some of these random people do become good friends. But I think most people who meet in this way continue to lead very separate lives. And somehow, that's even lonelier than living by yourself.
I was surprised at the generally positive publicity that living with total strangers seems to get. I'm always told that living with friends destroys friendships, and that when you live with strangers, you're "on your best behavior". Well, I can finally compare the two situations from my own experience. In my senior year of college, I lived in a house with 3 good friends and one stranger. There was drama sometimes, and lots of it. But at the end of the year, I emerged still friends with my friends. If I wanted to be alone, I could go to my room or the usually-empty running track near the house. But if I wanted to see my friends, all I had to do was walk upstairs to the living room. Now, I have to take a bus to see them-- any of them. For me, living with people who were already friends is the clear win. But, awkwardly enough, I'm not sure how to go about achieving that. It's not like college where everyone changes their housing at the end of the year.
Also, totally unrelated: Per one of your suggestions, I watched A Home at the End of the World. You're right, I really liked the unconventional family in the movie. And parts of it ("Come on, we're all beautiful and lonely here") were really funny, although others were quite sad. But I totally didn't read Bobby as asexual. I can see why someone might, although if I had to choose, I would definitely call him bisexual.
