Only on the lower East Side of New York do the houses of Capulet and Montagu survive. There they do not fight by the book of arithmetic. If you but bite your thumb at an upholder of your opposing house you have work cut out for your steel. On Broadway you may drag your man along a dozen blocks by his nose, and he will only bawl for the watch; but in the domain of the East Side Tybalts and Mercutios you must observe the niceties of deportment to the wink of any eyelash and to an inch of elbow room at the bar when its patrons include foes of your house and kin.
