One of the hardest things is watching your children learn that not everyone in the world is kind and honest. My 13-year-old son recently learned this at his school. He had been bringing his IPOD to school to listen to music on the bus ride to and from school. He always kept it in his backpack which was with him.
However, during a track practice, he had left his backpack unlocked the locker room. While he was practicing, someone went through his backpack and took his IPOD. He was shocked and disappointed that someone would do this. It was a valuable lesson but certainly a tough one to go through.
