Without trying to be sexist, my favourite analogy about the difference between man and women is that emotionally, generally, men are like dogs (an open book) and women are like cats (complex)....A dog will kill from instinct whereas a cat will often kill for fun and will play with its' prey while it is still alive....That's not to say that ALL women are like this but there are definately some that take great pleasure in 'toying' with people's emotions and if you are an 'open book' then you may well be prey for such women.
