Why do schools make kids do summer reading!

I dont understand this people. Its bad enough that we have to go to school. So why do we have to read during the summer. Its like summer school but still passing. The summer is so we can get away from school and have fun. not work! I just think schools should lighten up on us. We work for more then 150 whole days. Its a waist of a hot summer day. And im sure some of you out there think exactly the same. Am I right or am I right.
