Oh, I wouldn't change my personality in any way. I am who I am and I take pride in that. HOWEVER, ya have to admit, when you're told you're too fat/thin/critical/passive or whatever else you may (or may not) be - you think about it and wonder to yourself whether or not it's something you may want to change. For example, I was pushing 200 lbs last summer, and I was told I was overweight. I knew I was, too, and being told repeatedly that I should do something about it made me at least think about it. Don't get me wrong...it was more for ME than it was for them.
That's the point I was trying to make. I don't think anyone should change a damn thing about themselves to please others. It should be done for yourself only, but like you said...those who love you and are close to you may make "suggestions." Up to you whether or not you listen or take advice from 'em!
