Just stop. It's not your place to laugh or chide. Stop now. He may not realize what you are doing to him. STOP IT! He doesn't know, HE DOESN'T KNOW! What do you know? Does he go home and cry About the stupid pranks and Jokes you play? Is it a joke? It's not to him. He is human and He is worth more than you. The jokes are worth less than one laugh, But his life is worth eternity.
