I'd describe myself as an open-minded sceptic, even if that description makes no sense to anyone else but me.
From time to time, our letterbox goes once, in exactly the way it would if something had been posted through. It happened today, and one of my DCs heard it, as did I. My DC said 'Postman Pat' as he usually does when he hears the postman come. I replied that 'he doesn't come on Sundays', and went to the door, expecting something had been hand delivered.
Except, nothing had. And it's not the first time.
I could explain it if the wind was blowing or we had kids locally who could just be messing about, but neither applies. The weather is still and it's very quiet where we live.
AIBU to ponder the possibility of a woo letterbox?
