The aquarium tour guide explains how penguins mate:
a penguin brings the lady penguin of his choice a rock.
If she accepts, they will mate for life. End of story.
In the eyes of a child, this is love, and this is beautiful.
People who choose to mate for life start out much the same way:
the man brings the lady of his choice a ring.
If she accepts, they will mate for life.
In their eyes, this is right, and this is acceptable.
But people are not penguins.
And when they finally realizes this, people can be people again.
