Tyler's Melt down

So today I had a client coming over for a color, she has 4 kids but she only had her 4 year old and 2 year old with her today. This worked out wonderful for Tyler he finally had someone to play with besides Sydney (our mini dachshund). At about 11:30 it was time to go to preschool. Tyler was not having it he wanted to stay and play with the other kids. It could not have worked out any better cause at that time The kids grandpa came to pick them up. I tried to rationalize with my 3 year old son that Ashley and Ryan were leaving, and that if he stayed he would miss school and have no one to play with. I got the typical 3 year old answer. "But Why" So Brian just grabs him and puts him in the car. Brian said that a few blocks away he finally stopped crying. By the time they got to school Tyler has forgotten all about wanting to stay home. All I can say is Three year olds you can not rationalize with them!
