Revenge has never made me completely happy, but I do it a lot. I love to get even with people, and it is weird, even for me to say, because I'm so normally forgiving and kind. Of course, I only feel good about it the first couple of days, then I'm off depressed and feeling crappy about what I did. Some of the stuff in the past, that I considered revenge was pretty sadistic, but other times were pretty ridiculous, such as having sex in my parent's bed after grounding me, and such.
I have mixed and sometimes, hypocritical feelings against revenge.
