The first warm sun after a long winter is worth stopping in the middle of a sidewalk for.

Bodies keep a record of weather whether or not you are thinking about it. After months of grey, the first afternoon that is genuinely warm registers somewhere older than thought, which is why people go quiet and tilt their faces up without deciding to. It is a real event. It also lasts about a week before turning normal again.

When it happens, stop where you are for thirty seconds instead of walking through it. You will not be late. Let one good afternoon interrupt you rather than get noticed on the way to somewhere else.
