Oh, I don't know. You take one step out of someone's life and when you look back, they are different people. Better people. Worse people. Ready people. Not quite ready people. Sometimes I think people are just buffers between other people and total awareness. Maybe we'd know a lot more if we just didn't slow each other down.
I get too attached and I always expect that when things move too fast you'll understand when I let go. I always expect that you'll be hanging on my coat tails when I run and one day I can pick you up and we can finally run together. That's not how it is, though. Everybody is running a different race and once your fingers stop touching you are on different tracks, with new horizons, on the road to becoming different people.
I find that if I don't keep tabs too often then I almost don't recognize who it is I should be keeping tabs of. I almost forget why I should be caring so much. Why should I care about this total stranger just because we were once different people at the same time.
These are different times now.
