Re: Would you think this is rude?
I voted "other." Because it depends. Was she trying to joke around and was just giving you a hard time, or was she intentionally being a smart alec to annoy you?
If it was the first, I wouldn't see it as rude, and unless I was already in an irritated mood it wouldn't really bug me.
But if she said it PURPOSEFULLY trying to be a smart alec, then it IS rude and WOULD annoy me.
