didn't ever think of hugging her himself. It just didn't come into his mind.
He knew that sometimes she hugged him instead of explaining things to him, and he didn't like that. She didn't want to tell him why it mattered that she find the clean place, so she hugged him and said, "Oh, you dear thing," or "Oh, you poor boy." But that only meant that it was even more important than she was saying, and she thought he was too stupid or ignorant to understand if she tried to explain.
He kept trying to remember more and more, if he could, only now he didn't tell her everything because she didn't tell him everything and fair was fair. He would find the clean room himself. Without her. And then tell her if he decided it would be good for him to have her know. Because what if she found the wrong answer? Would she put him back on the street? Would she keep him from going to school in the sky? Because that's what she promised at first, only after the tests she said he did very well only he would not go in the sky until he was five and maybe not even then because it was not entirely her decision and that's when he knew that she didn't have the power to keep her own promises. So if she found out the wrong thing about him, she might not be able to keep any of her promises. Not even the one about keeping him safe from Achilles. That's why he had to find out on his own.
He studied the map. He pictured things in his mind. He talked to himself as he was falling asleep, talked and thought and remembered, trying to get the janitor's face back into his mind, and the room he lived in, and the stairs outside where the mean lady stood to scream at him.
And one day, when he thought he had remembered enough, Bean went to the toilet - he liked the toilets, he liked to make them flush even though it scared him to see things disappear like that - and instead of coming back to Sister Carlotta's teaching place, he went the other way down the corridor and went right out the door onto the street and no one tried to stop him.
That's when he realized his mistake, though. He had been so busy trying to remember the janitor's place that it never occurred to him that he had no idea where this place was on the map. And it wasn't in a part of town that he knew. In fact, it hardly seemed like the same world. Instead of the street being full of people walking and pushing carts and riding bikes or skating to get from one place to another, the streets were almost empty, and there were cars parked everywhere. Not a single store, either. All houses and offices, or houses made into offices with little signs out front. The only building that was different was the very one he had just come out of. It was blocky and square and bigger than the others, but it had no sign out in front of it at all.
He knew where he was going, but he didn't know how to get there from here. And Sister Carlotta would start looking for him soon.
His first thought was to hide, but then he remembered that she knew all about his story of hiding in the clean place, so she would also think of hiding and she would look for him in a hiding place close to the big building.
So he ran. It surprised him how strong he was now. It felt like he could run as fast as a bird flying, and he didn't get tired, he could run forever. All the way to the corner and around it onto another street.
Then down another street, and another, until he would have been lost except he started out lost and when you start out completely lost, it's hard to get loster. As he walked and trotted and jogged and ran up and down streets and alleys, he realized that all he had to do was find a canal or a stream and it would lead him to the river or to a place that he recognized. So the first bridge that went over water, he saw which way the water flowed and chose streets that would keep him close.
