My older brother just turned 27, has a fiancee and two kids, my nephew who is 2 years old and my niece who is ~6 months. Super cute kids. My brother and I used to be at each other's throats when we were tiny. During our teenage years we didn't pay much attention to each other at all, but now we get along pretty well. We're currently discussing potentially starting a small-time business together. He's more outgoing and less socially awkward than I am, but also more short-tempered and rash.

I'm 22.

My two younger sisters are currently in their sort of awkward teenage years, but they're brilliant. The older one is 17, she's more like me temper-wise, while the younger one is 15 and more like my brother. Those two are thick as thieves.
