In very rare circumstances is vengeance a necessity. You should use your energy for something more productive. Its normal to feel like you wnat it, but its just a feeling. The best revenge is living well. You suffer through it and you live anyway.
Life is full of bumps in the road and black eyes.
I think that everything is exactly what it appears to be. I just really try to go through life shitting on as few people as possible. I'd like to moon them all, but I don't really want to shit on them. There's a difference. But with age you learn to forgive people.
