Perhaps, but for many retired people daily attending to their lawn and flower beds is a source of great pleasure. I trust you when you say that your lawn is neat. But from the comments of some on this thread, I bet their lawns and property look horrible.
Just between you and me ...LOL
The man is in his 50's and lives with his mother. I have been here 10 years and have never seen any other activity there. They only come outside to pick up leaves and weeds on occasion. The have no veggie garden or any colorful gardens. Its a brick house with grass and some green bushes and shrubs. Blinds are always drawn.
On another note. There house is at a busstop for the local elementary school. When it rains we usually drive there to pick up our children. One time a womans tires were on the strip of grass before the curb and after the sidewalk. ( the town owns this little strip by the way) They came outside screaming at the mother to move her car or they would call the police.
Clearly there are issues at this residence. Bothering the police for a fence installation is just plain absurd.
