Dear Restraining Order...

Dear Bitter Amanda,

Recent life experiences have left me with a bitterness so intense, I can taste it like yesterday's hot dog. I crave something sweeter. Like revenge. Do you have any guidelines or tips on getting even?

Dear Restraining Order,
Ahh, hell hath no fury. It warms my cold, grey heart. I can only assume you're speaking of relationship-related scorn.
(If I'm wrong, email me again and I'll get back to you. But I'd strongly advise against using the word "wrong.")
Let's see what we can do for you, sunshine.
Try to turn your problem into an amusing anecdote. ("My boyfriend broke up with me by bringing me a present! I guess they just didn't have a greeting card with the appropriate sentiment?") Yours won't be as amusing as mine, but keep that chin up. In time it will improve. (Maybe. No guarantees. You might be one of those bad storytellers.) That way you can throw it around wherever you go, which is a subtle (and quite frankly, classy) way of bringing someone down. Making him the butt of every joke lets the whole world know that he was the butt of your relationship.
There are always the tried and true standards. The Chanel suit of revenge, these tactics just don't go out of style. Making sure that any girl he gets close to knows about his unadvertised traits is a good way to ensure that he is alone. ("God, I'm so glad we're through! I don't know how many more Friday night Lord of the Rings marathons I could have taken!") While you're at it, become friends with the new ladies so that he is in a constant state of AWKWARD.
Now...there are other ways to get your revenge, but it has been advised that I not endorse any of them. So you're going to have to use your imagination. *cough*spread rumors*cough* Excuse me. Rely on your bitter instinct here. *cough*syphilis is unattractive*cough* Damn, I'll have to have that cough checked out.
Hope that satisfies your craving.
Solitarily yours,
Bitter Amanda

PS- As for guidelines, I believe there is a phrase in the popular vernacular that sums it up. Go big or go home.
