When my nieces went home, I spent the evening with my son and nephew (both 12). We also went to see a movie (War Horse, which was very good!). The energy level between the girls and the boys was dramatically different. In the car, the girls were so chatty. They all had something to say and they wanted to say it all at once. I considered giving them a pen to pass around and telling them only the person with the pen could talk. In comparison, the boys seemed almost sullen. Most of our conversations centered on fun facts. They really seem to enjoy telling me things like how long a cockroach can live without its head.
It was nice breaking the kids up into groups like this. They each got to do the things they wanted to do and there was no fighting, whining, or bickering. I will definitely do this again!
