Without the awareness that we are supposed to be different, men and women are at odds with each other. We usually become angry or frustrated with the opposite sex because we have forgotten the important truth. We expect the opposite sex to be more like ourselves. We desire them to ‘want what we want’ and ‘feel the way we feel’. 

We mistakenly assume that if our partners love us they will react and behave in certain ways - the ways we react and behave when we love someone. 

This attitude sets us up to be disappointed again and again and prevent us from taking the necessary time to communicate lovingly about our differences. 

We have forgotten that men and women are supposed to be different. As a result our relationships are filled with unnecessary friction and conflict.

When you remember that Men are from Mars and Women are from Venus, everything can be explained.
