Is it normal to react this way
I once knew a kid and he told me stories of things he'd done. When I spoke with him, he was always very mellow speaking and never really reacted to anything. He told me about how when he was in fifth grade, someone had tried to cut his hair (jokingly, with kiddy scissors), and he ripped the scissors in half.
This guy was also with a girl. They broke up, and he got really angry. I told him to let his anger out by yelling, but he said that really didn't like to yell, and would rather hit something. So, he eventually punched a wall.
What I'm really trying to ask is if it's normal for a child (this guy was fifteen when he told me these stories) to react in such a way. He would always act out violently instead of yelling or something. Is this normal? Is this healthy? Is there any explanation for this?
