Sweetie, you already acknowledged it -- now leave it alone, and just go on like nothing happened, ok? No need to beat it to death. You didn't do ANYTHING wrong. You gave her a compliment!!! All you did is basically tell her that you thought she was GREAT!!!
So stop beating yourself up, okay? You're a great employee, and you must like your boss. So now let it go, okay? You're just fine. God bless and please take care of yourself. Big hugs, Lee
