Living with your extended family? Yay or nay?

[MrsMerryHenry]

DH and I have been considering getting a place with his sister, who is single with no children. We have one DS at the moment. We haven't discussed it with her formally but now DH and I are having second thoughts and need to weigh up the pros and cons.

I'm interested to know what other people think - both people who live with their extended family and people who would rather chew off their leg than have Great Aunt Ada shack up in the spare room.

I'd be happy to tell you about my experience. For the past four and a half years my husband and I have shared our house with my son, his wife, and two small kids. They have the floor below us and we have very clear rules about respecitng each others' privacy, not invading etc. And days may go past when we d on't see t hem and we always text or ring before visiting them, they are a bit more fluid with us.
So far it has been a thoroughly life enhancing and happy arrangement and we all envisage ad infinitum this way. If you want to chat mroe I'm [email protected]

Never ever ever ever ever ever ever ever ever in a million light years.

That's not really sharing a house though, if you have a house large enough to have 2 totally separate living areas and kitchens then it's more like having adjacent apartments.
Always having someone else in "my" kitchen or choosing what to watch on the main TV or entertaining their friends/ boyfriend in communal space so I feel I have to retreat to my bedroom like a teenager is completely different.
I'd feel disappointed if my son and his family ended up sharing a house with me, I want more for him.
