all of that is true.
but NNNPD is right too, kids are brilliant. i really enjoy their company (nearly all of them, anyway - this year i teach maybe two kids i'd rather vanished) - and i'm always learning my trade - making it better/more fun for them, and for me.
my ideal lesson is a laugh from beginning to end - sometimes they associate Miss Spanglechick with "fun" though, and think that when they step through my door, they can do whatever they think is fun - that's an understandable confusion; i just have to make them see that if they trust me to set the parameters and the agenda, they'll have fun anyway.
