I got my first concussion when I was around 8 or 9 years old. Playing football in the back yard with my older brothers and some friends. My brother (two years older than me) used to always use occasions such as this to show me how much tougher than me he was, so as I was catching a pass, he blind-sided me and knocked me into a pine tree, knocking me unconscious. A couple of years later I figured out what a huge pussy he was, and that I could kick his ass if I really tried. All it took was laying him out a couple time for him to get the message.
The last time I spoke to him was at Dad's funeral, almost 13 years ago, and the time before that was... fuck. I can't even remember.
