Men think in a straight line. It is a simple as that. We think linearly. Our main concern all day and everyday is getting from point A to point B. Nothing else matters. Now, if we have to get from A to C then we know how to get there. Now, maybe this does not make sense, but if I tell you, for example, that men think about one thing, what does that mean? Getting laid? Well...that is thinking linearly.
Women think completely different. They think more circularly. They think more about getting from A to Z while trying not get caught or stuck on any of the letters in between. Women will always think about things that men will never think about or consider until there is a need for it. The problem is that women get frustrated with us men because we don't think the same way or have the same thought process.
