There is a difference in a neighbor who is a few days late mowing and it's a little tall. We all get that. It's the neighbor that lets it get 2-3 feet tall which causes all kinds of problems for the neighborhood.
I have the opposite problems. Our neighborhood mows too much, makes us look bad. The guy behind us and to the right of us are lawn nazis, and mow twice a week and manicure the crap out of everything (one because he's an arborist, the other I just think can't stand his wife). The guy to the left is recently retired so he has nothing better to do. I feel bad going once every 7-10 days. Most of the time I can't even tell a difference in what I am mowing.
