Stuff comes apart.
An eggshell's never gonna come back together. A window will never unbreak.
It's called the second law of thermodynamics.
It's also called life.
Stuff rarely comes together, but it will always come apart.
Everything comes apart at some point. We all will. It's the law. It's what we're designed to do.
We have to face it and accept it, and try to hold it together, for as long as we can.
