Anger
What's funnier than what it does to me, is its ability to stick with me. I was angry yesterday afternoon, and it has barely subsided nearly 24 hours later. It always surprises me to go to bed angry only to find when I wake that sleep has done nothing to dissipate the feeling. I guess it is like many other emotions or feelings - if unresolved it is left to fester.
Bless Nine Inch Nails for "Pretty Hate Machine." I have yet to find a CD that makes me feel better when I am angry.
