What is it that causes the misunderstanding between the sexes?
Well its a known sociological fact that when men talk, they look at the person they are speaking too. When men listen, they stop what they are doing and look at the person speaking to them. Women on the other hand, do not necessarily look at the person they are speaking to nor do they as a rule look at the person they are listening too.
It is also widely recognised that men listen to the entire point and then may utter a single sound in acknowledgement of receipt of that point. Women on the other hand offer constant acknowledgement whilst listening using either body language or complex utterances.
