i'm sorry this happened =( but you know what, you're not alone....it's happened to all of us (quite a few times with me) and like lyndz said, you're remorseful about it and you weren't being a jerk intentionally.....it was just a faux pas. it happens. As long as you've realized and you'll know next time.

I have to remind myself "just cause it sounds good here (points to head) doesn't mean it'll sound good here (points to mouth) =)
