After the rain
The easiest time to notice a place is just after the weather changes. A path you have crossed a hundred times can feel unfamiliar when its dust settles and the stones darken.
Look at where the water gathers. A shallow hollow becomes a mirror. Drops stay on the edges of leaves long after the sky has cleared. Birds return to their usual calls one at a time.
There is no need to turn every walk into a project. One detail is enough to remember: the colour of wet bark, a reflection in a puddle, or the smell of the ground after rain.
