I don't think you should move the other stone.
As a matter of fact, I think you should consider
moving the other stone backs onto the sidewalk
to exactly that position where you would like
it to be. When I sent you my e-mail, I was not
asking you to do me a favor; I was merely stating
my point of view, and I am neither embarrassed nor
offended if you do not share it. The Town places
fire hydrants and electric light poles on that
strip of grass; it plants trees which grow to large
dimensions. All these are traffic hazards; if it's
important to you, why shouldn't you contribute a
boulder or two? If the Town doesn't like them, their
Highway Department, which is responsible for the
safety of the roads, can haul them off. Left in place,
they become the Town's responsibility, not yours.
The likelihood of legal liability seems to me
extremely small.

Your letter, obviously, raises questions of far
wider and deeper import than two measly stones,
questions which I may or may not address in subsequent
letters. For now, all I need to say is that I trace
all problems that I create for those who are associated
with me to myself. I try to understand how my personality
may explain our perplexities, and I would like, if it
were possible, to make matters better rather than worse.
