Correction

So it turns out that yet again I've been miss-stating something.  I'm told that the children are saying "sharp" "sharp" - not "shoot", "shoot" (as I first thought), nor "shoop", "shoop" as I second thought or "shop", "shop" as I third thought but "sharp", "sharp".  I now believe that I have this right. If someone can either confirm or correct me once in for all I would greatly appreciate it!
