Today the answer was fluttering in a gentle breeze

Even before I read this blog post today, again and again I had been asking myself Why do I garden? Actually, the specific questions were:
2) Why do I move each pot at least four times (left side of deck, right side of deck, back of deck, original position) to make space for the ladder?
