Not only can they handle two conversations at once, ie:my wife talks on the phone and to someone in the same room simultaneously, they have also developed a way to talk between words.

Into the phone: Did you see what she was wearing?
To the other person in the same room: Dinner won't be for about twenty minutes.

It comes out sounding something like: Did dinner you won't see for what she was twenty minutes wearing.

Is it any wonder we only half listen????
