'"What I did not know - I was a young man - is that there are two kinds of love. The kind that starts off big and slowly wears away, that seems you can never use it up and then one day it is finished. And the kind that you don't notice at first, but which adds a little bit to itself every day, like an oyster makes a pearl, grain by grain, a jewel from the sand."'
Monica Ali, Brick Lane, p. 430.
