Rectangle windows

Trav started a new gymnastics class today. It's the next age group up and doesn't require parent participation. It's also in a new city and building. Trav got a chocolate coin at the end of class, stamps on his feet, and a lot of teacher attention. He jumped and flipped and bear crawled and monkey jumped for an hour. When Fletch got home from work I asked Trav to tell his dad about his new gym class. Trav said, "Rectangle windows."
