Many boys and girls are heroes in their dreams," Dumbledore said quietly. He did not look at any of the other girls, only at her. "Fewer in the waking world. Many have stood their ground and faced the darkness when it comes for them. Fewer come for the darkness and force it to face them. It is a hard life, sometimes lonely, often short.

If I'm teaching deep things, then I view it as important to make people feel like they're learning deep things, because otherwise, they will still have a hole in their mind for "deep truths" that needs filling, and they will go off and fill their heads with complete nonsense that has been written in a more satisfying style.

Declaring yourself to be operating by "Crocker's Rules" means that other people are allowed to optimize their messages for information, not for being nice to you. Crocker's Rules means that you have accepted full responsibility for the operation of your own mind — if you're offended, it's your fault. Anyone is allowed to call you a moron and claim to be doing you a favor. (Which, in point of fact, they would be. One of the big problems with this culture is that everyone's afraid to tell you you're wrong, or they think they have to dance around it.) Two people using Crocker's Rules should be able to communicate all relevant information in the minimum amount of time, without paraphrasing or social formatting. Obviously, don't declare yourself to be operating by Crocker's Rules unless you have that kind of mental discipline. Note that Crocker's Rules does not mean you can insult people; it means that other people don't have to worry about whether they are insulting you. Crocker's Rules are a discipline, not a privilege. Furthermore, taking advantage of Crocker's Rules does not imply reciprocity. How could it? Crocker's Rules are something you do for yourself, to maximize information received — not something you grit your teeth over and do as a favor.
