No Fire Truck!!!

Yesterday while shopping at the outlet mall, I thought it would be fun for Collin to have a break from the stroller and play on some of the mechanical riding toys. Collin went straight for the one that looked like a fire truck. I put the money in the slot and the truck started moving back and forth. He did not care for that and told me "no". That meant he wanted off. I showed him that the buttons made the siren sounds that he makes when he is in the car with us. He was not amused and still wanted off. Not sure a good idea. Now I know.... I will wait a few months before trying that again.
