I found the following in Paul Auster’s Travels in the Scriptorium and hope he won’t mind me quoting verbatim: An old man wonders why a beautiful woman would go to all the trouble of taking care of him.
Why are you so kind to me, he asks.
Because I love you, Anna says. It’s that simple.
Yes, it’s that simple. Sometimes when one wonders how people can put up with one’s whims, one will have to remember that.
