If you don't mind!
1. an expression that rebukes someone for some minor social violation. When Bill accidentally sat on Mary's purse, which she had placed in the seat next to her, she said, somewhat angrily, "If you don't mind!" Bill (pushing his way in front of Mary in the checkout line): Excuse me. Mary: If you don't mind! I was here first! Bill: I'm in a hurry. Mary: So am I!
2. a polite way of introducing a request. Bill: If you don't mind, could you move a little to the left? Sally: No problem. (moving) Is that all right? Bill: Yeah. Great! Thanks! Jane: If you don't mind, could I have your broccoli? John: Help yourself.
3. a vague phrase answering yes to a question that asks whether one should do something. Tom: Do you want me to take these dirty dishes away? Mary: If you don't mind. Bill: Shall I close the door? Sally: If you don't mind.
