Law Enforcement

Last time Cal and I went to indoor park, I read to him the sign on the back of every ride-in car. It said that children can not "push or pull cars, speed, or crash into others". Although no one enforces these rules, I figure that I should at least *try* to do my part. Today Cal began his play time by pushing one of the big cars. I again read the sign to him and told him that he must ride inside of the car. Twenty minutes later, he drives up to another child who is pushing a car. Cal adamantly started pointing to the sign and said "NO PUSHING! The sign says no pushing! No pushing!" He was so upset that others weren't following the rules. I'm sure that if he could have written this child a ticket he would have! :)
