I don't take well to people who criticize you in the corner, giggling and laughing, I'd prefer to be told to my face and will even get angry about not being told to my face, but I'm ok with people talking about me.
I prefer for people to understand me, so if asking about me or discussing why I did this or did that (so long as they recognize my intention, or at the very least so long as their misrepresentation is innocent. [I'm ok with people misunderstanding me, it happens all the time, but I would prefer that if a person makes a mistake about me that it doesn't transpire in some negative way, or it changes their behavior towards me in a way I don't want. Basically so long as the misunderstanding is almost wholly inconsequential for me, I'm indifferent.] helps in understanding me, then i'm ok with this.
For this reason, even gossip is ok with me, so long as its not something I'm personally embarrassed about.
