I can't imagine a life with paparazzi everyday, of course we see celebrities getting annoyed and attacking them. too much of anything isn't good.
Obviously it's a very extreme example, I think in general everyone appreciates nice pictures of themselves.
I think so too, but often a simple asking of permission can completely change how you view someones actions. You're much more famous than I though. The only time I wind up having my photograph taken is when I walk behind someone taking a selfie haha.
