There are few pastimes more enjoyable than sitting in the window of a sunny restaurant with a café au lait and watching the streams of people moving by: obese multicolored tourists; slouching, loose-gaited natives in porkpie hats; slightly tipsy wedding parties; hipster upright bass players lugging their instruments to the next gig; people dressed in strange costumes and painted silver all over (there's a remarkably large number of these); an Abraham Lincoln impersonator who's very short and very irritable because he keeps getting mistaken for Toulouse-Lautrec; a husband and wife wearily bickering; a gaggle of giggling matrons holding gaudy go cups and bumping into each other; the same husband and wife leaning against the cathedral kissing; a couple sitting idly in a restaurant window, watching the parade and smiling.
