Taking your last paragraph to heart, I realized last evening why I enjoy watering the tiny patch of lawn behind my house. No less than five species of birds drank, bathed, and frolicked in the bounty of clean water, and that tiny connection to their lives filled me with a tangible intangible oneness of being, from which we humans are usually isolated in our techno-bubbles of linguistic chatter. It's definitely not natural avian twitter that depletes my enthusiasm.
