Why can't I keep my mouth shut? I kind of agree, no sense in stretching it out and bringing more attention to it. You already had a talking to by phone right. I would just let this sleeping dog lie. That being said you would know your office better than myself. My office is filled with a lot of hunting, drinking,truck driving, hockey playing, red necks, something like this would be a non-issue because it happens every once in awhile.
