A nice quote to begin with...

From “Send”:


“Sarcasm may be a less direct form of anger, but it’s still anger. The Greek root of “Sarcasm” means to rip flesh, usually with your teeth. When a wild animal bites your thigh, it is literally being sarcastic. Of all the tonal choices you can make in a correspondence, the decision to use sarcasm should be carefully considered, and almost always abandoned.”
