It's a woman's nature to deny her beauty. It's a man's duty to convince her of it.
At least I think it is my original. It came to me while driving home from work today. I was thinking about about how whenever I tell loving wife she is beautiful she will roll her eyes in that "maybe when I was young" kind of way.
I searched several quotation web sites and found nothing. If it is something I read somewhere and have kept buried in my unconcious I apologize to both my readers and the person who said it first.
I like it. I know it may be considered sexist in today's world and to some cynical people it may sound hokey, but I am comfortable with that.
