Why is summer so long?

For the last couple of months Derek has asked a recurrent question, "Mom, why is summer so long?" He also was very curious why school needed a break. I gave up trying to explain it to him. Needless to say, we have been counting down the days until school starts. Finally, Wednesday morning, Derek woke up and I could tell him today was the day. He was super excited, although we had to beg him to pose for a picture or too. Sean, however, was more than happy to oblige. Derek eventually decided he couldn't let his little brother be the only one wearing his Power Ranger back pack in pictures. Derek had no reserve when we got to the classroom, he barely said good bye to us before he was off playing with some of his friends from last year and a couple of new ones. Hopefully he continues to be so enthusiastic about school.
