As a kid I would be put to bed when my parents had guests and because I was such a show-off I would go to my mum's room, put on her nightdress and Jackie Onassis shawl, run downstairs, go outside, ring the doorbell and pretend to be one of the guests. I'd say, 'Hello, I'm Mrs. So-and-So.'
I showed that privacy was an implicit right in Jewish law, probably going back to the second or third century, when it was elaborated on in a legal way.
