Okay! So I talked to Professor Sprout, and she says that the Weird Sisters cellist,
Merton Graves, is a former Puff! And only two years older than I am, how'd he manage that?
So I sent an owl off to him and explained the situation, and got a reply today he understood why I'd rather owl him then any of the others, he was very sweet and everything is set! He gave me a list of things they'd need to pass on to McGonagall and a list of the groups favorite snacks. Apparently some of them are picky gourmets.
So Madison, everything's good! I warned him about the whistle.
