Funny moment

Today I was teaching Joshua White a piano lesson - our first piano lesson, and he was getting frustrated (which is understandable) because all of the sudden this person comes in to give you structure and teach you scales and it's not all that amusing.
The best part was, in the middle of our lesson, Joshua puts one hand on his head and shakes it a bit, saying:
"I think....I think we're just going to have to re-schedule."
Joshua is 6.
Priceless.
