Oh, yes, now this he can work with. Devin's expression turns smug, if a shade incredulous, and he laughs quietly. Someone doesn't like perceived criticism.

"Really, out of everything I just said, that is what you take from it?" Heather has just reached new and fascinating levels of self-importance. "I'd expected​ better from someone your age. I'm sure you've lived long enough to see people like him, but whether you've actually been where he is - that's an entirely different matter. I'm trying to offer you perspective, but if all you're going to do is take everything as criticism and don't demonstrate to your student the ability to listen to others who might have valuable insight, then perhaps he does need a new instructor." It won't be Devin. Probably. He doesn't do teaching; he does riling. "Age does not mean wisdom, after all."
