Why men should not write about women, just like women shouldn't write about men...

In my opinion i just hate reading any story or book about a male gender author writing about what women want. The same goes for women writing about how the mind of a man works. I also hate having to sit and watch movies about it. Only men know what men want or what men are really thinking. Women break their heads over the mystery of the male mind. I don't think when it comes down to writing a book or making a movie we are well aware of how different all women are. Just like i feel the same way for men, but they know and they bond with the idea of thinking that they are such a mystery when really we are all the same way.
