This is good poetry. The sunshine is perhaps always with us. Even in the night from the moon it glows as reflected light. The sun gives life and it makes our lives bright. It gives us warmth and it is our primary source of light. It makes trees make their food through photosynthesis. It is what our greens are all about. A promise of returning back in the morning is reassuring. Especially after a very dark night. It is very near to how joy and sorrow follow each other. There is always light at the end of the tunnel.
