I like the saying, "Revenge is a dish best served cold." To my mind this is saying that if you give your vengeful thoughts time to cool off, you probably won't act on them at all, and isn't that best? When I was young I was very hot tempered, often became angry very quickly and while perhaps firing off a nasty retort to someone may not precisely fit the definition of revenge, it feels close enough to me. Age has mellowed my temper and experience has taught me that flying off the handle is not a good choice. I was never one to seek revenge in a physical sense, such as tearing up another's possessions, creating a hassle for someone in the workplace or causing trouble for others in any way. Revenge is not sweet. It is very bitter and never satisfying.
