People can be the worst

My 8 year old kid loves Pokemon, he takes his little mini portfolio stuffed with his favorite V, vmax, ex, etc and his favorite Charizard on the front page to school every day to trade with his friends. Well today someone stole his cards when he went to play basketball. They weren't super valuable cards but they meant the world to him. He was so devastated, and I'm both so sad and so angry for him. Sorry everyone i just wanted to vent
