You were ok in this situation;
HOWEVER, I would NEVER,
NEVER, put my hand or other body parts, on ANYONE, without legal cause (i.e. I am in a correctional institution and am legally required to physically intervene when emminent danger exists). Your intentions were on target, but the method of execution (Pun intended
) was not the best choice.
Was that "coach" out of line? ABSOLUTELY, but it is not justification for you to get into a power struggle. Do not lower yourself to his standard.
Yes, I realize the testosterone was flowing at full bore. Ain't it great!
