Endings have a sound, and the end of rain is one of the clearer ones. Noise drops out, drips take over, birds start up again, and the air goes soft. You have been inside hundreds of these and registered almost none, because nothing demanded it. Attention is the only ticket, and it is free.

When the rain is tailing off, stand at a door or a window for the minute afterward. Do not take a photo. See whether you can hear the change in two stages, the stopping and then the street starting up again.
