When I mowed my Father's lawn, apparently I cut over a few inches onto his neighbor's grass. He would do the same occasionally. She called police.
For the past few years she installed wooden and rebar stakes and rope to divide the property lines. She was also upset that we crossed the property line to turn the mower around. Yet she does that all of the time.
She is a wacko man-hater.
My Father "banned" me from mowing his lawn because I would purposely step over her barriers and stuff like that.
Yet at the same time, she complained that nobody "helped" her clear the snow from her driveway in the winter. You can't get any more crazy than this woman.
