It's very easy to get worked up about fools. I've both been worked up, and had co-workers on the ledge of irrationality, with a fool as the cause. In my experience most folks classified as fools simply have different priorities and aren't fools - but that's immaterial for this post. When dealing with fools, remember to answer the following:
1) Who is the bigger fool - the fool, or the one being controlled by the fool?
2) What is a fool but a wise man's teacher?
