A prior neghbor let me run a long, narrow flowerbed along HER side of the sidewalk dividing us. She moved out, and a real ##@#$%## moved in.
I had to move that whole bed off her property, so I repossesed the soil I had made and wheelbarrowed into it. Fortunately, the underlayer was rock-hard clay so it was easy to tell "whose soil was whose".
The wierd thing iks thaqt I mostly had tall things that would have screened my yard from her view, and she considerts my yard messy, and is very concerned with appearances. I think she cut off her nose to spite her face! But then she cut down eveything living she could in her yard, including two good trees and a flowering azealea!
She only had ONE spot left with any decent soil, so she set three huge, heavy ceramic pots on top of that soil (I guess to crush any earthworms ... the pots ar still empty.
It takes all kinds!
