I have a brother and we are not close and never have been. It is most likely a personality thing as we are complete opposites. He is awesome and a nice person, we just have nothing in common. I always wanted a sister but it never happened.

To be honest I don't know any siblings that are of the opposite sex and are close.

Do you know any close pigeon pairs/siblings of the opposite sex as kids and/or as adults?

My DH and his older sister are very close. She ended up marrying his best mate.

My kids are 22 months apart and are great friends. Even now at 14 and 12 they get along briliiantly most of the time. I can well imagine them being good friends when they are adults as they are very much alike. Although I do expect it to get a bit rockier over the next few years.

I have a few friends with very close brother/sister relationships. One of them has a sister who she can barely stand (and the feeling is mutual) but two brothers she adores.

I have three sisters, and DH has two brothers. I'm closer to one of his brothers than I am to my sisters. I don't think gender decides it as much as personality does.

My niece and nephew. They are 16 months apart, and adore each other. One is 10, the other 12, so I hope it lasts. They are currently best friends, and happily hang out with each other all the time.

I think it's a personality thing.

My kids are currently VERY close and get on very well - but they are only 3 and 4 so I don't know how long it will last.
I was very close to my brother probably till he finished uni - I've lost a bit of respect for him over the years because of the way he is living his life, and I wouldn't say we're close anymore, because whenever he spouts an opinion on anything I feel like "sort out your own life first mate, then comment on others..."

DH is close to both his sisters, but probably not as close as they are to eachother. That said, they also have vicious fights with each other, which he doesn't have with either.

My dad is closer to his sister than any of his 4 brothers, by a very long margin.

I don't think gender really plays a part at all.

My DD2 and DS are 23 months apart and the best of friends. They can play happily all day together! They are nearly 3 and 5. Hopefully it will continue!

My brother and I are incredibly close. We have always gotten along well, I loved him from the minute I saw him and our relationship's evolved and changed over time but never not gotten long. When he was a teenager things switched from me being protective of him to him being protective of me. And now we're sort of easy-going and equal and I still feel a bit "my baby" about him.

My childhood BF and her older brother are also very close. They live together now and her brother is helping parent her child. I grew up friends w/ both of them.

My DH and SIL are very close. There is a 3 yr gap. They always have been close. They/ we have the same friends and socialise together a lot.

My niece and nephew are 10 and 13 and have always got along wonderfully.

My brother and I did not and do not although we are fine now that we no longer have to live together.
