Several years ago a neighbor and I started a garden that bordered both our properties (no fence). We planted all sorts of plants and with proper weeding and watering it was really looking good. Unfortunately my neighbor moved and the new neighbors (as nice as they may be) have no interest in the garden. Their side has gone unwatered and unweeded for over a year now. I have come to the realization that it is now almost impossible to control the weeds that are now taking over my part of the garden.
Weeds are easy to grow, gardens are not.
That is a very deep analogy. Unfortunately, many people will not comprehend it. But it is good!
