How does the narrator describe Sonny?

From the text:

"When he was about as old as the boys in my classes his face had been bright and open, there was a lot of copper in it; and he'd had wonderfully direct brown eyes, and great gentleness and privacy."

"I told myself that Sonny was wild, but he wasn't crazy. And he'd always been a good boy, he hadn't ever turned hard or evil or disrespectful, the way kids can, so quick, so quick, especially in Harlem."
