Once when I lived in Memphis I had a yoga teacher. She was off the deep-end yoga mellow lady. She also looked about half her age and I thought she was pretty cool. She used to talk about going camping and how much coordination that used to take for her. She was more comfortable in the city, walking on paved surfaces because she said that when she walked on rocks and grass, she could hear them protest. And once she put a campfire-hot pot down on a rock, and she heard it scream!
If rocks can yell, trees might have eyes. Enjoy!
