"Now what?" said Aunt Petunia, looking furiously at Harry as though he'd planned this.
 - Harry Potter and The Philosopher's Stone

Harry could - he could do things, and he pretended they were accidents.

He didn't mean it.

He thought, and thinking is only thinking and the teacher said that some thoughts are bad, but if you keep them in. If you keep them in, then everything will be just fine.

Harry is just fine.

Harry is naughty, Aunt Petunia says, but Aunt Petunia is a liar.

She lies about:

Dudley in the bath -- he was just watching, just watching, that's all he did. His hands were in his pockets when the bubbles popped up, round and soft, on the surface of the water.

The spiders in the garden -- Uncle's legs swelled up, so large and fat and funny, and he darted back into the house so as not to laugh. He laughed anyway, but no one saw. 

The old woman across the way, with eyes like pencil ends -- some people just get sick. They get sick and don't come out anymore.

There was a happening, sometimes, and the world let him watch it.  There was a ripple, and it was like something had wrenched inside him, but it wasn't him (even if it came from him, and felt solid in the best way, and like Christmas maybe feels for the boys and girls who get it).

It is a secret, and he has never had a secret before, because it's only a secret if somebody wants to know. When they notice.
