If i was the teenager in the story and that story happened to me i would feel very weird but also confused. Firstly cause i didn’t think anyone would react like that and be as friendly as he was. After all of that ended i would understand that this man is right and that i shouldn’t do what i did before so i wouldn’t steal from anyone again in my life but try and find a job .Also i would understand that it is nicer for everyone if you are friendly to everyone than if you disrespect them.
