I’d rather you just tell me instead of you going around telling people how miserable you are or being subtle because that just makes it a lot worse for both of us. Even if you can’t bring yourself to tell me directly just ask a friend or something to pass on the message because, funny as it may be, I can’t read minds or always notice when I’ve done something wrong. Don’t worry about offending me – I feel more offended that you’d rather tell a bunch of strangers what you feel about me instead of talking to me about it.
Also, while I don’t like being wrong, I’d rather recognize that I was wrong, and work against those mistakes, than to continue being wrong.
