My cell phone does this all the time, it drives me nuts. There was this one time, though... I was mean, I couldn't help it. I was talking on the phone with a then-friend when I suddenly realized after she ignored my fifth question/comment that the connection had gone wonky-- but it took a good five minutes of her talking before I figured it out. So I had a very bad idea-- I decided to wait to see how long it would take before *she* figured out there was a problem. Over ten minutes later, she *finally* interrupted her monologue to say "hey, are you there?" I think that was when I realized that when it came to our "conversations" I could pretty much have pointed the phone at the wall and went to dinner and it wouldn't have mattered much. :/
