Please talk me out of it!!!!!! I really want to tell my co-worker off.....?

She may be jealous of you. telling her off would probably only set her off. i wouldn't be fake with her anymore as she can probably tell. i think you should be blunt but nice and she will respect you more. it seems like shes trying to push you to say something mean and then feel like the better person or see who you really are. show her but not in the way she thinks
