I'm never quite sure what to do when I'm chatting with someone and all of a sudden, they grab their hip or their purse, whip out a blackberry/phone thingy and start typing. With a phone call, I know to stop talking and wait for them to finish. But do I keep talking while they are typing or wait until they are finished ?
This is assuming of course, that they don't do the proper thing and say "Excuse me please" and then step away for a moment.
