Still no post...

Is it true to say "A watched letterbox never flaps"? Does it carry the same sentence as watching a kettle?

Thats a silly saying anyway... of course the kettle will boil! It has no idea that you're watching it. Does it? I mean, how would it know? Telekenesis or whatever is appropriate? Can a stainless steel appliance be psychic?

Or... do the very expensive models, (even Porsche make kettles now you know), have built in human sensors? Maybe they disable the boiling function until the appliance is left to get on with its work in private. I never realised kettles were such shy appliances.

So, it seems, is my letterbox.
