Bradley,
From the posts I have read on this Board, you sound like a really funny person and women LOVE a sense of humor. I personally would have thought it was cute if you had said, "Sorry but my conversational skills are very low at the moment but so i have to go but maybe I can get your number and we can carry this on another time?" I would have thought that was funny and honest and you can't get much better than that! Good luck!!
