Here, where it is so easy to dance, the whole street moves in solidarity with the silver-haired couple performing a living room waltz across a public square, feet crossing and twisting and crossing back to the sultry sounds of the swaying cellist and his violin friend, playing not for money but for the love of it, and of these streets nestled below the chiming bell-tower, where fountain water rushes out, flowing onto marble steps pulsing with life while old ladies in matching scarves shuffle by in time with skipping school children laughing in harmony, and even the prison next door pounds out La Traviata because here, where it is so easy to dance, the whole street moves.
