Different periods of my life have had different theme songs.
When I was in high school, my theme song was "Nobody's Girl" by Bonnie Raitt. I was a serial dater but never opened myself up to whatever poor guy I happened to be dating at that point. Dating was a one-way process to me: I basically had to be as cool and mysterious as possible, until I was certain
that the guy was head-over-heels in love/whipped over me. Then my job was done, and I moved on to the next guy. It was all very Dorothy Parker of me. Not very mature, I know. But hey, I was 15. Cut me some slack.
When I was in college, my theme was "Good Intentions" by Toad the Wet Sprocket. So many mornings I would wake up and shake my head, "I can't understand what I did last night." And, while dating a toxic person for more than a year, the lines "I'm not afraid things won't get better/But it feels like this has gone on forever" reverberated in my head.
Now that I've aged like a good cheese, I've mellowed as well. I'd say that, for the past few years, my theme song has been "Float On" by Modest Mouse. It is what it is, in a matter-of-fact, marching-through-life kind of way. Shit happens, but we just keep going. I smile every time I hear it.
What are your theme songs?
