Men do fall in love BUT they are not thinking in the same way as girls do...
A girl has first to be physically attractive so that a man wants to go out with her... then little by little the feelings come into his brain and he falls in love!
For girls, it s slightly different... it first comes to our brain... and if we find the man can bring us respect, tenderness and pay attention to what we are.... we ll fall in love, even if he is not as attractive as others (=they are convenient to us!)
I think, actually, it s very difficult to be a man.... because of all which was said about them (virility and so on...)
