If you're feeling like phsyically acting out on it, I suggest the following:

- Go to the batting cages and hit some base or softballs.
- Go to the driving range and hit some golf balls.
- Get some blow up punching clowns from the store and place them around the house.

The balls and clowns can represent the person you're angry at and you can hit them all you want and not be doing any damage to yourself or anyone else.

I've heard that pounding on pillows also works, but I personally enjoy the other three methods myself.

Sincerely,
Pfrog!
