My brother and I were born in the overgrown back garden of a house in Paddington sometime during February 1995. When we were a few days old, our mother was bitten by a rat and the man who owned her tied her to a fence post and left her to die. For nearly a week, she survived on water which was leaking from a pipe and she fed us till she died. Then Diana, the lady who lived next door, rescued us. Being too young and stupid to recognise kindness, after a couple of weeks we ran away and started to live rough. It was the beginning of my fascination with refuse. Even now, with two square meals a day and more biscuits than are good for me, I find black bags and waste bins irresistible.
