Jade Fern Grove mossy stones to tell the weather

Pheiros watched the strange man look at him upside down, a shy smile curving his lips before it instantly fell away when asked if he was tall enough to reach the moss. Um... was all he said at first because he had no idea what to say. He was frozen with insecurity. First of all, he was most likely not any taller than the stranger was, so there was not really any hope that he could do better at reaching this moss. Second, he had no idea what moss was. He thought maybe he was referring to the soft green stuff that clung to bark of the tree, but he realized just then that he didn't actually know what that stuff was. He looked around awkwardly, wondering if should lie, but he couldn't really come up with a lie either. 

Um, I'm not sure he finally answered. He wasn't sure if he was tall enough and he wasn't sure if he knew what moss was, but he also wasn't sure how to explain that without looking stupid.
