Walkie talkie

Have you ever seen people using their mobile phone as a walkie talkie? They hold their mobile phone to their mouth with the ear piece away from the ears and when they want to hear the other party, they then put the ear piece to their ears. I find it obsolutely stoopid that some people will talk like that. To me, it just reflects that these people would rather talk and the other party listen, which explains why they need not hear the response or feedback from the other person as they rattle on. Imagine when the other person on the other line is doing the same... both are talking assuming that the other party's listening but actually it's just 2 monologues.
