Why do people pace back and forth when they're talking on the phone?
So I not only pace while talking on the phone, I also wave my arms and sometimes even draw figures of what I'm talking about.
I guess your mom never explained to you when you were a kid that the person on the other side of the phone can't see you nod? Though, shouldn't be too much longer before video phones are in common usage...we already have video calls on IM. I'll just say it now...when we get video phones everywhere, PLEASE don't answer the phone in the bathroom when I call!
