So, someone told me I was pretty for a fat person.
user
Wow, I’m sorry that happened.  What a thing to say!  Fat people are people too, and I’m so sorry someone felt the need to say something like that.
assistant
Yeah, it was a backhanded insult.
user
Well, I hope you were able to move past it and ignore him/her.  You’re a person, and a beautiful person.
assistant
Well I want to get back at her.
user
Uh oh, this seems pretty revenge-oriented.  Why do you want to get back at her?
assistant
Because it was mean of her.
user
Well, sure, she said a mean thing, but do you really want to take revenge on her?
assistant
Yes.
user
Do you want to hurt her feelings?
assistant
Yes, I do.
user
Are you sure?

Uh oh.  I think you need to back away from this idea of revenge.
