I had an elderly neighbor lady who moved in next door. We soon learned to avoid her. The final straw was when she accused us of looking into her yard through the knotholes in the fence that separated our back yards. No, we were not looking into her yard, but I decided to print up some eyes, glue them on some poster board and staple them on the fence over the knotholes.

Petty? maybe. Satisfying, YES!
