Quote 25
He said that I was clearly a very logical person, so he was surprised that I should think like this because it wasn't very logical.
I said that I liked things to be in a nice order. And one way of things being in a nice order was to be logical. Especially if those things were numbers or an argument. But there were other ways of putting things in a nice order. And that was why I had Good Days and Black Days. [...]
I said that when Father got up in the morning he always put his trousers on before he put his socks on and it wasn't logical but he always did it that way, because he liked things in a nice order, too. Also whenever he went upstairs he went up two at a time always starting with his right foot. (47.2-4)
This once again points to Christopher's desire for stability and structure. Here, he makes the argument that not only do we all want some structure, but we all find individual (and often arbitrary) ways to do so – anything to establish some control over chaos.
Quote 26
And sometimes Mrs. Shears stayed overnight at our house and I liked it when she did because she made things tidy and she arranged the jars and pans and tins in order of their height on the shelves in the kitchen and she always made their labels face outwards and she put the knives and forks and spoons in the correct compartments in the cutlery drawer.

On the surface, this quote points us back to Christopher's desire for order in the world around him. But, beneath that, it says something about his relationship with the people in that world as well. Here, the role of "mother" in Christopher's household is arguably reduced to cleaning the house and arranging the things in the kitchen. As long as Mrs. Shears does that, this suggests that her installment as surrogate mother is okay with Christopher. Is that a fair judgment to make?
Quote 27
I wondered whether I should open the envelope because it was something I had taken from Father's room. But then I reasoned that it was addressed to me so it belonged to me so it was OK to open it. (149.50)
Is Christopher using twisted logic to justify actions he very well knows are wrong? Or is he proving that although common sense suggests these actions are wrong, they're actually logically sound?
