How do you make them understand? What don't men understand about women?
As many men as there are and as many different women it's a hard question to answer. I know that now I'm older I understand more and then if I apply that to a new woman I will be so far off base it wouldn't be funny. Some women are somewhat easy to understand and others don't understand themselves. The same goes for men. It can make his life easier if he does understand her or least try's.
