Personal tragedies aside like the loss of a friend or loved one I would have to say...

Music. Damn Billy Joel singing Piano Man gets me every time. My room mate can always tell how I'm feeling because of the type of music I listen to while toking. Or when something happens to someone who makes the music I listen to. Dime dieing was hard just because I have been listening to Pantera since I was 10. Layne dieing was also hard. Kurt and Bradly Nowell, more so Brad because I had some older brothers of my friends who were really into them.

As you can see I have a very music centered life, too bad I can't play an instrument to save my life. I really don't see it as a bad thing, but I'm always the guy that people as when they want to know the name or artist of the song. As long as it's rock I can pretty much name them all when I listen to them.
