Most of us have heard about four letter words. The minute you mention them, many immediately think naughty words. But this time of year, hope is a four-letter word. As is soil, seed, rain, bird, root, stem and grow. Four letter words-- every one. As I roamed about my yard planting hollyhocks, bachelor buttons, sweet William, zinnias, and other butterfly attractors, I kept thinking, I hope for moisture and that the hard little hulls I tucked in the earth would sprout roots and stems to unfurl skyward under warm, spring sun.
