I know I'm not the GM for shinysweety's PMD RPG or a moderater for the RPG forum (much less, I'm not even a mod at all), but you can't just have random interactions. Yuri, Fai, and Rei are all at Golden Sky Wood, not at base. Same goes for You and Lula. Lula never said ANYTHING about a rock, much less throwing it at someone.
No offense meant, but if this is your first RPG, I would be glad to give you a few pointers! ^^
