Sometimes I imagine, if I can travel back in time, I would change this and change that. You know? How things might turn out differently if I had been more out going in high school or had the courage to talk to that girl. Or maybe if I actually studied more in college though I was sure I didn't want to be an economist.
It's kind of like these soap bubbles, eh? Once they burst and go away, that's it. You can't bring that bubble back and all you can do is look forward to the next bubble. Wobbling through the air. No point in thinking about the past, got to look forward to the next wobbling bubble. Heck, even the Doctor can't go back into his own history.
