I'm going to describe someone as fat while talking to another fat person
Are you trying to start trouble?
I can do whatever I want, she's a good friend of mine
You can speak how you like but she might get offended. You should try to not make your friends uncomfortable.
I never said that I'm going to do that. I don't mean anything else.
Well you should just expect if you bring it up she could be hurt. Do you have anything else you would like to discuss with her?
