Violins in Cellos

9-yr-old boy, uses a school violin.  The string department at school (including the instrument storage space) is housed in an area called the chalet (I'm not quite sure why).  This was while he was packing up.

Boy: I'm going to Sydney for the whole holidays.
Me: And are you taking your whole violin?
Boy: Nnnnoooo... Unless I have a smaller case.  Can I get a smaller case?
Me: You'd only be able to get a smaller case if you detached bits of your violin.  [Unfortunately, he looked enthusiastic with this prospect].  Which is the same as breaking your violin.  So, don't...
Boy [all packed up]: Oh... I'm going to put my violin in the cello now.
Me: In the ... chalet?
Boy: Yep. 
Me: Yeah, don't try to put it in the cello.  They... wouldn't like that.

[Cue giggles as he leaves the room, encountering a mate who had just finished his cello lesson].
