Have you ever done something for revenge?

have you guys ever done anything to get back at someone for what they did to you? if so what?

Well, lets see, theres one time in particular which I am not the proudest of. Years ago I was managing a retail store and had a couple of beautiful girls working for me. Both had shown interest in me and was not shy about it. I had a guy friend of close to 11 years come into the store and fall instantly in love with one of those gals. I did what any good friend would do, I hooked him up. Shortly after they began dating my friend became a total douche and stopped returning me or the other guys in the groups calls. Each time we did set up a time to all hang out, he blew us off. After about the 50th time and months of him being a prick, I decided to throw a little kink in his relationship. I met up with his new dating friend (almost girlfriend), knowing that she already likes me, I told her that I had some feelings for her as well and that it would be great if she gave me a shot and let me take her out one time. She took the bait and I ended up using her to get back at him. Needless to say, my conscious got the best of me and I eventually hooked them two back up and they've been together 6 years now almost. I still don't talk to that douche bag nor his girlfriend.
