Got a girl I work with. Nobody talks to each other much because she is always listening and joins in the conversation with her own input. I was talking to someone about a job and asked if I needed to be in the military and she chimed in saying her friend was not military and got the same job and the guy I was talking too said no. I need a professional thing to say when she rudely joins the conversation where she was not welcome. I need it to be something that, if put on paper, wouldn't sound too harsh or anything because she is the type to report you if you tell her something she doesn't want to hear such as: "well, nobody asked you, mind your own business". She reported someone for saying that and the person got a slap on the wrist. Thanks!
