Once, and this is the ONLY time I remember ever being struck aggressively in any way (I'm a very peaceful guy, though my mouth says otherwise). Was about 7 at the time, and I was waiting in line in gym class for some odd reason. Fourth grader cut in front of me, I got a bit upset and called him stupid. He didn't take it well. He *****-slapped me, but I didn't feel anything more than a tickle and kicked him in the nuts while the whole school cheered me on--okay, I cried like a seven year old who got *****-slapped. But, anyway, that's about all. Yeah. Have A nice day everyone.
