I find the sound of stepping on leaves very amusing. The very sound instantly makes me smile, and I feel the need to go and find more to step on. There is something very refreshing about the crunch sound one hears upon setting their foot upon an unsuspecting leaf. It is a simple act, most often done unexpectedly, and yet it feels great. It might sound harsh, stomping on leaves, but it really makes me feel young and happy.
The wind also is very pleasant. It is the same wind that has been blowing since time began. So many things it has been through and yet it is still there, reliable and reassuring.
Just a few random thoughts I had. Nothing too crazy.
