Isn't man a fool?

Joe's (not me) response to my snowfall blog below got me to thinking about a couple of things I learned as a kid:

1. Never judge a day by the weather.
2. A poem:

Isn't man a fool?
When it's hot, he wants it cool.
When it's cold, he wants it hot.
Always wanting what is not.
Never happy with what he's got.
