No, but my sibling and I are very different people. We have three things in common: the same parents, our eye colour and our love of 80's music. After that, we are generally opposites! Imagine the coolest kid in a school year living with the deeply un-cool one, and you get the picture of our childhood relationship!
We got on better after my sibling moved out. We don't talk or message each other, apart from polite annual messages to say happy birthday and merry Christmas. We don't see each other apart from at occasional family events. If we weren't related, we wouldn't care to know each other, as we have very different lifestyles and interests. We only hear of what the other sibling has been up to from our mother, who obviously keeps in touch with us both, and sees us separately.
Our mother frequently wishes that we were closer, but that ship has long since sailed.
I have had friends over the years who were very close with their siblings, and are in daily contact as adults. I often wonder how they forged such a close bond.
I hope that, if I'm lucky enough to have children, they might be close with their sibling(s). I'm unsure as to whether they would be permitted to infect their cousins with any perceived genetic weirdness of mine 😁
