It was an egregious extension of the opt-in nature regarding privacy now - everyone is starting to think it's OK just to put a phone in your face, film you, photograph you or whatever. Very often it's for no other reason than the fact that they can.
Well, OK - I partially accept that's the way the world is going, that's how our culture is shifting, and how people are relating to each other differently.
But it's not happening in my house. On my turf, you can bugger right off and I would regard this as the same as getting into my personal space 'bubble' in a physical sense.
