He’d always wondered about his neighbour.
He was a nice enough guy, but just a little bit odd. Most of the time he came across as being perfectly sensible, but there would be those odd occasions when he’d say the most ridiculous things. It had been going on long enough that he could see that it was getting worse. They’d be chatting away quite normally, usually over the garden fence, the way two old retirees would, when out of the blue, he would do it again. He would come out with something quite absurd. At first, he thought the man was pulling his leg because he would have such a straight face, while at the same time saying something completely ludicrous. This was no longer the case. In fact, he had hinted at the idea that maybe the man needed help.

The whole thing came to a head the morning he was pottering in the garden, when the man next door came to the fence and beckoned him over.
On this occasion he wasn’t talking, he was whispering. He looked around nervously. “It’s Sally,” he began.
“What about her?”
“She’s trying to kill me!”
“What are you saying?”
“Look my friend, you really do need to get some sort of help.”
“Why’d you say that?” the other whispers.
“For heaven’s sake, man! You live on your own with your dog, and Sally’s a German Shepherd!”
