We had so much fun together growing up making up our own games and activities.  My brother  and sister and I would set out in the morning trying to figure out what we were going to do for the day. Then our little sister, Damita, (whom we called geeky)would say.."ooh, I know what we can do today, we can build a clubhouse".  Now don't ask me how many summers and weekends we attempted to build this clubhouse, but that was our mission. I am sure there were other things she suggested to do, but the clubhouse one just sticks out because it was said more.  It wasn't until recently while watching Phineas and Ferb with the kids, did I realize why she like it so much..she was a version of Phineas..that was so funny to me and I had to share it with her son Tray, who laughed.
