Well, not really hate. Just screamingly jealous of him. The interesting thing is that such an innate ability (and it's absolutely innate; it's genetic and cannot be learned beyond assigning names to the learned notes/tones) has little if anything to do with any musical gift the kid may or may not possess. It's strictly a memory function, in such a case called "pitch memory".
