For the end-of-year band concert, they pooled the three local elementary schools and had them play together. Unfortunately, you can't see Leo as the trumpets are in the back, and he's short. Apparently, he was seated next to some girl from another school who decided that she like him. She showed him how much she liked him by hitting and scratching him and generally trying to get in his face.
