Are you a Guy?
Guy rule #4371: GUYS do not apologize to other guys, or to groups of people in general either. If in the event that you have been a major duckhead, it is acceptable to acknowledge the fact that we acted as a duckhead at a specific instance in time, but NOT to ever admit to feeling bad about acting that way.
EXCEPTION TO RULE #4731: You are allowed to say your are sorry to your wife/girlfriend, but only when no other person(s)is around, excluding any children that you both are the parents of.
