You Said It

Junior Quartet yesterday morning.  I'm recovering from a cold - so, odd voice (if present at all), sneezy, sniffly, and grumpy.  Only 2 girls were there on time.  They were actually taking initiative and tuning their violins on their own.

Violin 1: Oh, Viola isn't here today.
Me: Why not?
Violin 1: She's at...
Me: Is she doing some... Sport... thing?
Violin 1: She's at [insert some regional thing] cross country.
Me: Okay.  Now.  You hear how my voice is still a bit weird? 
[Girls both nod, wide eyed]
Me: Well, I still have a cold.  So.  I need you all to behave.  Really well.
Violin 1 [giggling]: It's a good thing Viola isn't here then. [Viola is very chatty]
Me: Yes. Oh.  Well, you said it...
