Swan to find true love?

Well, I'm searching the animal kingdom for true love -- and I think there is hope: swans mate for life. Something I have yet to figure out how to do.

The male hunts for food and builds the nest while the female sits on the eggs. It's a little old fashioned, but I like it, the idea of sitting around while the man builds the house and gets me food that is. I mean really, why do we make love so complicated?
