Hmm.... My theme song? White and Nerdy by Weird Al.
No, I wish. Well, I am white and slightly nerdy.
When I was a little younger, mid-late teens, my parents would argue many times a day. They never divorced, but threatened it many times. Around that time, my theme songs were "Wonderful" by Everclear and "Family Portrait" by Pink. Both sad by beautiful songs.
Right now, I really feel "Life Starts Now" by Three Days Grace. I'm trying to deal with my many life problems that I've just tried to ignore, and become a better person from it. =)
Oh, also "Bad Reputation" by Joan Jett and the Blackhearts and "I Don't Care" by Fall Out Boy.
That's a lot of songs, but I left out even more. Music is my life. =D
