Footprints

So, I've heard it said that people come into your life... and some of them stay forever... but most of them leave "footprints". Meaning, they effect you, and then they move on, you lose touch, something along those lines. And that's great and everything...

But what if you're the sand that can't let the footprints go. What if you stay behind just staring at them, while they (the footprint leavers) move past you? What then?

I guess, what I'm saying is, how do you go unscathed? How can you keep that footprint from continually hurting you/affecting you? How do you become the "footprint leaver" and not the one that gets walked on?

meh.
