Shoulder Devil

One of my junior quartet violinists came to see me first thing this morning - before rehearsal - to organise a lesson time for the first week back.  The violist came in as well.

Violin: So, can I organise a lesson time?
Me: Sure.  What time would you like?
Violin [looking at the blank page]: Ummm...
Me: Really, you can have pretty much any time.  Does Tuesday work for you - same day as quartet?
Violin: Yes.  That would be good.  Umm...
Viola [peering over her shoulder]: You should do 12:30.  Then you don't have to last until lunch.
Violin [shaking her off]: No.  Um.
Me: Do you want 12:30?
Violin: No.  Um.  When else would be good...
Viola [whispering]: 12:30 12:30 12:30 12:30 12:30 12:30
Violin [actually batting her away]:  No, not 12:30.
Me: When would you like then?  Before morning tea?  Before lunch?
Viola: 12:30 12:30 12:30 12:30 hee hee hee I'm like [giggle] one of those [giggle] shoulder angels... oh wait... um... shoulder... devil...
Violin: Could I have... 9...?  Or 9:30...?
Me: Sure - which one?
Viola: Pick whichever one you want [whispering] 12:30 12:30 [normal] pick whichever one [whispering] 12:30 12:30 12:30
Violin: Agh!  Um -
Viola:  Pick whichever one you want [whispering] 12:30 12:30
Violin: Oh shush!  9:30 please.
