When I am angry I can be a really funny person to be around, or a very dangerous person to be around. On these days I prefer to wear my shirt that says:
I'm so dangerous I should come with a warning label.
The last guy I was with actually picked this shirt out for me, and told me it fit me well.
When I get angry I tell my mother we need to go for a car ride and just drive around aimlessly, blasting music as loud as possible. We then proceed to dance around in our seats like crazy lunatics, or we pull into a parking lot, and we get out and dance around the car while people look at us like we're nuts.
I also go for a hike up in the bluffs and sit on the highest peak looking down at cars that look like ants. While up there, I scream as loud as possible, getting rid of all uneeded negative energy.
The last thing that I do when I'm angry is spar. Having a sword fight with old newspaper dowls can really release tension as long as you don't seriously hurt your partner. Last time I did this I broke my partners dowl in half because I let loose to much tension.
Warning: The last way of getting rid of anger is not recommened for those who are not trained in the arts of weaponry.
