I have two. They're both older than me. The eldest one is a very caring person. But she's also very intense and can be a bit bossy. She's great, but in small doses. I'm a very different kind of person - much calmer and much less inclined to tell other people what to do.
My other sister is more like me. However, we both have very busy lives, so we don't get to meet up all that often.
I have two brothers also. I was closest to my younger brother when we were small.
If I needed help, I could call on any one of my siblings and they'd be there for me 100%. But I don't actually socialize much with any of them and never have. We get together for family events or big birthdays and at Christmas but otherwise, we do our own things.
