Ouch!

The truth is that it's difficult for me to have them digging in my yard, even when I know that the result will be a lovely herb bed, with Arts & Crafts masonry, that will spread blessings and health all over my small yard. But every shovelful of dirt tugs at me and I can feel the ditch dug for the foundation of the raised bed in my own depths. I think that this is part of what the Earth demands. You can dig me, but you must dig and be dug in return.
