Each morning and evening, and whenever I can, I take off my sandals and walk upon the earth. I feel refreshed with the softness of green touching the soles of my feet. There is a small area of grass near where I am staying in the desert where I can do this. Maggie, the dog who I am caring for and walking, enjoys chewing on the grasses, too; in fact, she insists on taking us there. Dog knows. God knows.
