Older brother was extroverted, very smart but under achieving, had a very dominating personality, highly prone to agression, protective of family but also quite bullyish (to toughen you up). We both had fathers out of the picture though at 2 my mother married a guy that did more than a great job filling the father figure position (even if quite distant emotionally) but my brother grew up most of his life without a father figure... hes about 16 years older than myself. I was quite an accident (all my siblings older than me).
