I want to slap my little cousin because he kicked me in the groin
Are you serious? Why did he kick you in the groin?
I believe he was just showing off for the other kids.
Well, he shouldn't have kicked you like that. But slapping him isn't the answer either.
Who cares, I want to slap him. He's so annoying
You should never retaliate and hit a kid for any reason. You should just let it go.
