When they came by one day the dog was quicker than I was & it got out the door & started barking. I knew the dog was being friendly but they didn't so I said in a panicked voice "DON'T ANYBODY MOVE"! They froze while I got hold of the dog by the collar & the dog & I went inside when I turned back to the door they were headed down the street.
Another time I worked with 3 brothers, they were brought up as witnesses & said next time when they approach tell them that you've been shunned (they aren't allowed to talk with those that have been shunned). I tried it & they did a U-turn at the the head of the driveway.
