When my son was in kindergarten they went on a field trip to the zoo. I was one of the chaperones. It was my first time and I was kind of nervous about how it was going to go.
Things were going okay but I seemed to have one troublemaker in the group. For the elephants, sometimes they were outside or sometimes they were inside the building. The day we went they were inside. While we were on our way out, I was counting the kids and the troublemaker was missing. I was frantic having all the kids run around and look for this kid.
All of a sudden troublemaker jumps up from the side of the water fountain where he was hiding from us, just laughing and laughing. It wasn't too funny to me. I almost had a heart attack ;-)
Every time we went on a field trip after that, I always tried not to have this kid in my group. If I did, I made sure I kept a closer eye on him.
