O, thou art fairer than the evening air
Clad in the beauty of a thousand stars.

Hamlet: The air bites shrewdly; it is very cold.
Horatio: It is a nipping and an eager air.

If we cannot end now our differences, at least we can make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.
