I would like to know (if you do this) your comments to or responces to people who are rude and oblivious about their cell phone use. I'm not the most tactful about this as I usually run into it in places like the library where I don't think of it as being a problem. other placers I can get away from it, but in a captive space, I'm sorry to say, my judgement comes up - I don't have a lot in general, but about this I do. So, any suggestions for a graceful way to address it?
