My nephew was doing that and when he was 14 he kicked my ass and I'm strong. Now at 17, he gets me down on the floor and has total control over me. He's about my height 5'7 and weighs like 140 lbs and can KILL Me if he wanted. He shows me how to fight sometimes, but I have no one to practice on ;-)
you know I think he may have wanted to. He did say "I would grab u there but then I would be near your boob" but then he made the gross "that's my aunt's boob" face
