Leo Tolstoy 
Where There is Love, There is God Also 

In the town there was a shoemaker by the name of Martin, who lived in a basement with a tiny little window looking out into the street. Martin could see the people pass, and though he only got a glimpse of their feet, he still knew every one, for Martin could recognize people by their boots. Martin had lived in that basement for many a long year and had numbers of acquaintances.
