Chatterbox

At the start of ensemble rehearsal, one of the cellists (who sits inside 2nd desk) came up to me.

Girl [smiling nervously]: Um... Can I ask you a question? 
Me: Sure, what is it?
Girl: Well... and I'm pretty sure you're going to say no...
Me [suspicious]: Uh huh...
Girl: But I want to ask you anyway.
Me: Okay. [wait]
Girl: Is there any chance I can sit next to G today?
Me: Umm...
Girl: It's just that, um, you might have noticed, I sit next to... um [tries to find a polite way to say this] well, um, she's a bit of a chatterbox. [No kidding.  Chattiest child in the room, ever].
Me [trying not to smile too much]: Ah, yes... I had noticed that.  G would have to sit in the back row with you though - have you asked her if it's okay?
G [jumping into view at hearing her name]: What do I have to do?
Girl: Sit next to me, so... the chatterbox... can be not next to me.
Me: So we'd have S and C [the chatterbox] in the front, and the 2 of you at the back.

G was fine with it, and it turned out to be really good for C to sit right under my nose.  Of course, it meant I had one very energetic (and thankfully, very capable) cellist sitting next to a very energetic and chatty cellist...  But the chatterbox didn't move her chair around or move over to talk to the double bass or run outside randomly or any of the other things she does that are not sitting quietly.
