I am that way too - candidly - I want to continue to be the quiet, meek type and not ruffle any feathers.
Someone told me the other day that I was too nice!! I told her I couldn't be mean to the person (the woman was scheduled to do a trade show this past weekend with me and canceled the day Before we were to leave, I had to scramble and find someone else!) I just said okay, to her reason and hung up. Of course, I wasn't the boss either. Just a go between. I don't think I'd ever make a good boss. I'd let someone walk all over me, cause I wouldn't want them to be mad at me!
