Yeah, if he ever comes at you like that again, do not hesitate to teach him a lesson. I had to do it to my freinds lil bro.

The fucker came at me with a knife once, he was probably about 12 also, I was 17 he lunged at me and i grabbed his arm and I flipped him on his back, and came down on his chest so hard with my knee I knocked the wind out of him and I'm lucky I didnt break his ribs. Then I gave him a punch to the jaw about as hard as I could, then grabbed him by the jaw and forced him to look me in the eye as I shook his head and yelled right in his face "Mike, you little fucker if you ever fucking come at me again with anything even resembling a weapon, I swear to God I will fucking break you, even if it's you god damned nerf gun" I then gave him one more backhand hard. then let him up. It happened so quickly I know it scared the shit out of the little bastard. He got up left the knife where it was and left the room wideyed.

It's funny cause if you met me you'd know that's not like me at all, Im very slow to anger, and I'm a generally peaceful person. It's funny but my freind said before they shipped him off I was the only one he saw, that he thinks truly scared Mike.
