No. All of our siblings and inlaws only talk about themselves and never ask about our lives or our kids. The conversations are totally one sided, on both sides of the family.

My SIL is one of my best friends. We see each other probably 3 x week. Oftentimes, she's easier to hang out with than my husband (her brother). My other SIL is great too, although I see her less frequently due to distance. MIL, not so much. She's a nut job.

I have 2 SIL and 3 BIL's. I would be friends with BIL # 1, because he is nice and we have similar interests. BIL # 2 I wouldn't be friends with, but I'd happily hang out with him in a family-oriented situation (the way that I see him now). BIL # 3 has never spoken a sentence to me, so I don't think that we'd be friends or hang out if we didn't know one another. SIL # 1 is very smart and does super interesting work, but barely looks up from her phone and generally only says mean or off-putting things. As such, I wouldn't be friends with her. SIL # 2 is sweet, but very neurotic and insecure...I'd like to think that we'd be friends if I was not married to her brother, but I think that it's tough to be friends with her because she's always in a lather about something and so insecure that she can't say anything of significance about herself.

I don’t have any brothers-in-law, but I would like to be friends with my sisters-in-law. Unfortunately, I have nothing in common with my husband’s sister - and my brother’s 2nd wife is a nut job. The first one was smart enough to run.

My mother met my step-father because I was dating his son. We broke up after a few months (was just a college kind of thing) but they stayed together, eventually getting serious and married about ten years later.

My BIL married, normal life. We are friendly enough and probably would stay in touch like ex's (Facebook, Christmas card, etc)

Great question (title made me lol) and great thread.

No, honestly not. Not because of any drama, just not in my orbit, so we'd never really cross paths.

Somebody of them. One BIL is a complete weirdo and lots of fun. He was exposed to dry cleaning chemicals en utero.

to answer OP no I would never choose my BIL or SIL as friends in real life and I have almost zero to do with them in real life.

No way. One of my SILs is just a terrible person -- self-centered, has no filter, vapid. My other SIL is fine, but I doubt we'd be friends. She's nice enough, but kind of a bump on a log. We don't really have a lot in common.

I love all my sibling in-laws. I look forward to seeing them at holidays. We've vacationed together and had a lot of fun. They're interesting, kind and caring people who adore my kids. Some of them are people I don't have a lot in common with, but there are several whom I would definitely be friends with even if we didn't have a family connection.

I wish I was cool enough to be friends with my husband's sisters if they weren't sisters-in-law because they're amazing!

I doubt if I'd be friends with my cousins if we weren't related.

No and I'm not really friends with them now. I care about them and we have a pleasant time when we're together but we just have very little in common. I am a little closer to my brother's wife because she is more high functioning. My husband's sisters have some self-inflicted challenges that I can't connect with.

My SIL is nice, smart, and gracious. She is also 13 years younger than me and our interests or friends groups don’t overlap.

No. They are so boring. Nice, but annoying. And boring.

My brother has somehow managed to marry the most kind and caring woman, after a series of unfortunate relationships. We love her, and are friends.

DH’s 3 sisters are all nice people. The oldest is a bit spacey, and I don’t think we could be friends. The other two, absolutely! While I can tolerate all their spouses, I wouldn’t want to be friends with any.
