Of course the ability of a man to coax out smiles and laughter in a woman is important, especially at the beginning of any relationship. That, according to surveys, is what women want from life. A man with a good sense of humour. They don’t want to hear your views on apocryphal scripture or string theory. However there’s a flaw here. Because if a woman likes you she will, at least in the early days of courtship, pretty much laugh and smile whatever you say. And if she doesn’t like you, you might just as well be talking about apocryphal scripture or string theory.
