I just want to say, even though it may have been a conscious decision on the author's part in this instance, I'm so appreciative that you said this. I'm a very fledgeling writer, and I'm ignorant of most of the technical things that make for great writing. "Show, don't tell" is going in my "writing notes" book right now! Don't stop giving the positive feedback, because I know there are others like me who read these comments especially for these bits of advice!
