I agree with bee84, as long as nobody is being taken advantage of, I don't see a problem with living at home. (Although my parents do refuse to let me pay anything.
) Other people seem to have a different opinion.
Regarding living with a woman, that's where I'm not sure. I actually do not know what I want. One hand, I'm too much of an individualist to be living with someone without it going awry. On the other hand, I guess if I met a woman who really got me (and vice-versa) it could actually work out. It's hard to say.
And yes, I do notice having less and less in common with my old circle of friends, with a few exceptions they all started a family. That's definitely not for me; not the way they go about it anyway. It's too "normal" I guess.
