When I last went to a supermarket
my list was in my head and it was clear;
whatever the infinite choice on offer
I was there for what I needed, no more.
There was no point in buying
what I could not carry home
and what I could not store there.
As I saw the 'sell by' dates
I realised I had one of my own.
I had better do something useful
before I reached that time,
or at least learn how to quietly
live within my income.
