I was at school and yesterday was about to be over. I let this dude see it for a few minutes. We were friends for a while, but more like associates. Anyway, he gave it back and asked to see it again a few minutes later. I walked toward the door as the bell rang and I tried to get it back but he kept walking. He is about 6'2 and big. I'm about 5'6 and a little muscular. I grabbed him but he had his hand wrapped around it and kept pushing me away. He called a group of his friends that were about to jump me to keep me off of him and he disappeared.
