But why do Czechs use only one ear? Are they able to multi-task in their listening? Does it mean that they listen in mono mode, while, as we are all ears, we have surround sound? I tend to think they are just emphasizing that if you go to a Czech office you should be very patient, since they usually don’t speak English, and in Czech they use just one ear to listen to you. Of course, they mean that they are one big ear, doing nothing but listening. So, the meaning is the same, just from a different perspective.
