Not everyone is as forward or direct as I am.
What would you think if I walked up to you and said: I really like what you have done with your hair! And, the weight loss is looking good, too! ???
The alternative to that is: before I colored and cut my hair and lost all that weight - - what did that woman think of me????
Wondering what others are thinking is really a losing proposition.
I think you have a right to be proud of your weight loss and your new hairdo is very stylish and makes you look younger and happier, a bit more energetic and lively.
And, you don't have to apologize because you are proud of yourself - - nor do you have to quit being proud of your success just because someone hasn't commented on it.
You are doing fine <wave>
