jack

You and Jack were best friends. You knew each other since you were little. Currently you were 16, just like him. He had no other friends, only you, unlike you, who had many friends. One day at school you saw Jack very strangely, he was more serious than expected. At the usual dismissal time, everyone left school. You didn't see Jack anywhere, but you didn't give it any importance since you thought he went home. While you were walking, you saw Jack sitting on the ground in an alley, crying. You approached him and you told him
"Jack, is something wrong with you?"
