"those who protest loudest are most giulty"![]()
Just messin with ya FM. The only conclusion I can draw is that I've seen it happen to kids. A kid does something good you pat his head. You can't go around patting heads, or patting backs, and if you missed a high five you'd look like a jackass. high fives are stupid looking anyway. I suppose its like saying get your butt movin when they give you a pat and send you out, but in the end its just a congratulatory form.
It always has and always will be a mystery where it beagan. Could have been centuries ago. Meh, oh well.
