My wife is furious at me for spending £250 on a new doorbell.
We live in a flat in a Victorian conversion and share a front door with a complete busy body. She tampers with our mail and answers the door when she hears our doorbell (whether we're in or not).
I suspect she's 'not well' and don't want a nasty confrontation but we had to do something about the constant invasions of our privacy. We can afford the bell which connects to wifi and rings silently on our mobiles.
