I wouldn't beat yourself up too much about it.
Sh..
*AHEM!*
STUFF happens.
We're all human and almost all of us react to common situations oddly sometimes.
Funny story (to me anyway):
Standing at the vending machines at work one day, the cafeteria filled with all the most stuffed shirt females in the company, (I never felt it coming), my body decided to let loose the loudest, most embarrassing sounding flatulence in my entire life. It took me so off guard all I could think to do was loudly proclaim, "Whoa! There the hell did THAT come from?! EXCUSE ME! I had NO idea that was coming!", then left to feebly attempt to stifle my uncontrollable laughter at my desk.
Moment like that don't do anything more than prove we are human just like everyone else.
Trust me, they've all done it too, and in time not one of them will remember it. They will remember their own moments though.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
