A night walk lets you meet the neighborhood after its public purposes have changed.

The same street is not one place. At two in the afternoon it is a route to the shops; at eleven at night it belongs to different people doing different things, and the buildings look like themselves rather than like their function. Nothing has changed except the purpose the street is being put to, which turns out to be most of what you were seeing.

Walk a route you know at an hour you never use it. Take no destination, notice what is open, and let the place show you the part of itself your usual timetable keeps hidden.
