some times a someone's story touches us for some reason or other. you feel empathy for the boy who died. it touched you deeply enough to speak to your subconscious. time will make it fade away
sorry to hear that, have you spoken to anyone about it? maybe a school counselor or someone like that? i hope it stops haunting you so!
i feel more for the person he harassed, who finally snapped. sorry, but 13-14 is plenty old enough to know that you shouldn't be an @$$hole.
