I played basketball in college, and there's one game that I scored 35 points so I must admit as she was getting close to that 35, I was getting nervous that she was going to break the record that I held her. She blew it out of the water and kept going. It was fun to watch. The whole crowd at Carver chanting your daughter's name is a pretty cool thing.
