I am in danger of becoming known as a peeping Tom as a result of my wife's obsession with the safety of our dog. If it wasn't enough that the man opposite is always looking at us, she now believes that there is a second 'evil' man (she calls him worse than that but it is not repeatable here) standing stock still at the bottom of our street, staring at our house, with the intention of stealing the dog. There are 15 other houses between ours and where the man is supposedly standing. I need binoculars to see that far yet even then all I can spot is a rather nice tree in blossom. She will not have it and insists that he stands there hour after hour, day in day out ... until we go that way when he disappears. It is pointless telling her that she is mistaken - nothing wrong with her eyes - yet I don't feel that I can say it is true. Diversion doesn't seem to work. Telling her that the dog is perfectly safe with us doesn't work. How do I get her to stop looking out of the window and telling me over and over how worried she is?
