Bare feet...
I love the feeling that comes when it's a cool, breezy evening and you go outside and you stand on the cold grass, in bare feet, and watch the sun go down…
Or when you walk across a beach after dark, and just listen to the water and watch the stars, in bare feet too…
Or when you walk through a the woods at midday, and feel the shade, and see how the sun makes splashes of gold on the worn dirt path—and for that to be ideal you have to be in bare feet again. (I think the bare-feet thing helps you to feel closer to it all, or something…)
