while mowing the lawn this evening ( due to earlier heat ) and nearing the end of it at what I thought was 8:30 P.M. I notice the neighor coming towards me from the front of his home across our driveway and onto our back yard to confront me about how his wife and him can't relax with lawnmower running at 8:50 . I said I didn't realize how late it was and I'll be done in 5 minutes or less . So he calls me every name in the book and sticks his middle finger right in my face . In return I say to get off our BLANKING property and he then calls me more choice words while walking away to his home and back inside . Others in our neighborhood mow lawn in the evening due to heat or other reasons and not a peep . We've had the same neighbors throw some mild insults at us in the past , but never expected this . Quite sure he had a few beers . We've seen him with a beer(s) many times and a bit tipsy on a few occasions . We try to be good neighbors and respect others privacy and property . Just can't win .
