I have a next door neighbor who's always short of cash
This neighbour is aware I have a little stash
Every second friday I await his usual knock
A three day loan of twenty pounds at exactly 10 oclock.

This has become a habit, these loans to my friend Jack
I do not mind him asking as he always pays me back
He needs some gas and electric, it's not good to go without
That and more dubious substances, of that I have no doubt

But then it got me wondering, this money I do lend
Cash in perpetual motion, seems like it will never end
To and fro and back and forth for all eternity
Am I the one who lends to him, or does he lend it to me?
