My oldest son was all state in soccer. The next boy was all state in football and his team actually was AAA football state champs the year he graduated. They were 3 years apart.
I used to sit and the stands and just yell, "Play Soccer!" He played since he was five. I still had no idea what they were doin' when he got in HS. When I hollered play soccer, the boys would just look up and laugh and just shake their heads. I continued to embarrass him until the last minute of his last game. I still tell him it's gay.
My next son. Funnest 3 years of HS I had. Watching him play and actually being able to talk with him about every practice and game.
