Rough as life can be, I know in my bones we are supposed to stick around and play our part. Even if that part is coughing to death from cigarettes, or being blown up young in a house with your mother watching. And even if it's to be that mother. Someone down the line might need to know you got through it. Or maybe someone you won't see coming will need you. Like a kid who asks you to help him clean motel rooms. Or some ghost who drifts your way, hungry. And good people might even ask you to marry them. And it might be you never know the part you played, what it meant to someone to watch you make your way each day. Maybe someone or something is watching us all make our way. I don't think we get to know why. It is, as Ben would say about most of what I used to worry about, none of my business.
