"- Nice! Yeah, that sounds like an excellent mana-building technique, and there might even be more than three people in the school who'd trade you something for copies of the sheet music you got from it!"

"Huh! If I'm doing it in my head I won't get any sheet music but if it'd be worth writing it down I can try!"

"...Right, sorry, I'm really not a music person so I wasn't sure what to picture there. But - I do actually think that could be worth something, in here, though I guess if you were planning on that you might want to ask around first and pick the musical you know well enough that the most people would be excited about. We're - kind of short on fun entertainment, in here? And most kids can't afford to trade for just that, obviously, but sometimes the big enclaves can. It's good for morale and all."
