misunderstanding between men and women

What do you think is the greatest misunderstanding or misperception between men and women?

This topic is really interesting ! lol
But it's too difficult to write about it.....

I think the way to use the email will cause the gretest misunderstanding between men and women.
In my opinion, women tends to want many emails from their lovers. On the other hand, men don't want to send emails so often.
I think that may cause misunderstanding.

Men don't reply soon or text quite often. Women think it is the sign that the wen don't love them a lot.
But men don't mean that.
There is a very big difference. Of course, it depends on people though.

What do you think about my opinion?
