Today for show and tell I've brought a tiny marvel of nature: a single
snowflake. I think we might all learn a lesson from how this utterly unique
and exquisite crystal turns into an ordinary, boring molecule of water, just
like every other one, when you bring it in the classroom. And now, while the
analogy sinks in, I'll be leaving you drips and going outside.
-- Calvin, "Calvin and Hobbes"
