Oh, so true about image. I almost blew mine out of the water. Lack of sleep blocked the common sense alert. Being on here is just like in face to face situations. Once something comes out, it is hard to clear the bad taste.
As for walking out not paying attention. I have gone out with my work shirt inside out and backwards. Didn't notice till the tag itched my throat. I was almost late to work due to that darned snooze button.
