My father is becoming that paranoid old neighbor, and it breaks my heart. He has fallen prey to all the symptoms Sleeps With Butterflies mentions, and his personality has taken a hit. It also really doesn’t help that he keeps the tv on and spends all his time watching FoxNews.
The other day, he was ready to call the police on a bunch of kids in the park across the street. Because they “didn’t belong there”. Never mind that the kids were all under 12, well behaved, had a dog with them, and it was two weeks after the end of the school year. It took me 15 minutes to talk him down.
