I found this quote in Jane Austen's Mansfield Park. She's describing Fanny Price's home at Mansfield, but the words exactly remind me of the atmosphere I try to maintain in my classroom (Room 2).

"[In Room 2], no sounds of contention, no raised voice, no abrupt bursts, no tread of violence, was ever heard; all proceeded in a regular course of cheerful orderliness; everybody had their due importance; everybody's feelings were consulted."
