First of all, don't judge. Instead ask, why would someone tell someone to change anything? At the time I was devastated that I was doing something that wasn't "acceptable." However, that tells you how limited my thinking was back then and how I chose to have one person decide if I was "acceptable" or not. Now, however, I believe it had nothing to do with me at all. There was something about that person that needed to be changed or addressed and they chose to ignore it and instead direct their unhappiness toward me.
