burning low - with apologies to dirgewithoutmusic (смешанная)

I wrote something based on an ask that dirgewithoutmusic got on tumblr, where someone asked about a fic where Draco becomes friends with Harry Potter as kids. I wasn't very happy with their comment that Draco Malfoy's racism against muggleborns was an "inherent part of (his) character", as I think racism is taught. I also didn't like that they said "if you want a rich, pureblooded, old-name, but-not-wizard-racist kid for Harry to befriend, we have Neville." because the chemistry would be totally different. I'm not changing a part of Draco. I'm just developing him a bit earlier.
(I also wrote a gay version. If anybody wants it.)

He heard about Harry's stag patronus and found him in the library. "So yours is a stag, huh, Potter." He said, wringing his hands behind his back, unsure of what else to say. How do you explain jealousy that isn't quite jealousy? How do you explain worry but in a more hating way? How do you say "Hey, I'm sorry I called Buckbeak a chicken," without embarassing yourself? He held his breath while waiting for Harry's answer, but he didn't need to.
Harry smiled, a hollow, tired thing, and said "Hey, you'd get there. And, y'know, you could just call me Harry."
