The buildings I&#x27;ve lived in were built in: 1910 (Lower East Side), 1920 (Yorkville), 1915 (Kensington), 1928 (Brighton Beach), and 1910 (Upper East Side), and all of them were awfully thin. Maybe we have different definitions of paper thin, but I have always been able to hear my neighbors: walking, talking, playing music, taking a shower, or watching TV.
