This could strain your relationship with your neighbor.
Seriously, I can't imagine shooting the kid next door. It is possible that the elderly couple had known the kid his entire life.
To continue living next door to the parents after this might be impossible for me
“It is possible that the elderly couple had known the kid his entire life”.
True but sounds like the homeowner probably saw the gun he raised first. I feel sorry for this man and his wife. They are battling her cancer together and now have to deal with this stress.
Maybe he was rotten from the beginning, just like the boys who grew up next to my parents. In their golden years, my parents (and all of their neighbors) were harassed by those rotten boys, beginning when the boys were small and then later when they were teens. (These days they're in and out of prison.) The so-called "parents" of those boys were no good, too.
Or maybe I'm wrong. Maybe the neighbors of this senior couple were nice, and the parents just didn't know what their son was capable of doing. But, I tend to picture the type of "family" that lived next door to my parents. I'm glad this couple is all right.
