This reminds me of the Salvation Army bell ringers at Christmas time. I know this is not what you intended the poem to be about. My uncle is a captain with the Salvation Army and every year at Christmas we set up at various local stores and ring the bells. We don't sell or push anything and people give so freely. Truly a blessing as was your poem. Such powerful words in such a short poem. You have mastered this concept of conveying a point with few words. Marvelous Job.
