Does it matter which way it goes? It has to start from somewhere and end some other were. Sometimes it runs on the surface sometimes it flows far underground. It sows dreams on one bank and sorrow on the other. What it takes from one it gives back to the other.
I have a beginning and an end. Between the beginning and this end, what I do is of no consequence to me. What gets done is. Until the time my time runs out, in your banks I will stay.
