I had an old guy from New Hampshire that moved next door to is when I was 13 or so.
Some friends and I were thrown a football in the front yard and landed in his yard. He came out and told us if we go on his yard again to get it he was going to shoot us. That was the first of many arguments between my parents and him.
You can threaten me all you want but threaten my wife, son or dog and he would have bitten off more than he can chew. Dad always says "You can't fix stupid".
