I know I've probably said this before, but when I was a small child, I was taught to be quiet in the damn library.
Me too! Now the library is just as rowdy as any street corner, and the librarians don't say anything about it!
It's because everything these days has to be "people-friendly". The trouble is, though, that it seems that people are only really people when interacting with other people- if you just want to sit quietly and read a book, you don't count as a real person, just as a stick-in-the-mud spoilsport who is ruining everyone's fun.
Today there was a little boy who was screaming "I won! I won!" at a volume that was loud enough to be painful at the other side of the library, and noone made any attempt whatsoever to shut him up or at least explain the concept of his indoor voice.
