We are creatures of comfort.

We take comfort in things known,
Things that are guaranteed,
Things we've tried before.
We're afraid of letting go of things we love,
Things we held dear,
Things we think we can't live without.
We regret doing things that changed our situation,
Things we could've done differently,
Things that, if said, could keep someone close.
We cling on to memories, people, feelings, objects, places and hopes. It's our very own inertia, and we just can't picture life as we know is without them. It's like they're integrated into the very core of our being, our history, our destiny, our present. Even when these things slip away, we grasp at their afterglow.

No, there are some things we just can't let go of.
