The Gardener 52: Why did the lamp go out

Why did the lamp go out? I shaded it with my cloak to save it from the wind, that is why the lamp went out. Why did the flower fade? I pressed it to my heart with anxious love, that is why the flower faded. Why did the stream dry up? I put a dam across it to have it for my use, that is why the stream dried up. Why did the harp-string break? I tried to force a note that was beyond its power, that is why the harp-string is broken.
