Someone has been at my studio desk...

I was lying in bed this morning and heard some papers moving around in my studio area.
I asked, "Whooo's there?"
I heard nothing.
"Nick?"
"yeah Mom."
"don't be writing in my book please."
"Okay Mom"
"And leave the check book alone also!"

As I finished that last statement I heard the patter of little feet scurry down the steps. To my surprise, I found a check written to "school is exit" (I marked out info due to a crazy world we live in) and found dash marks in my "artsy journal" .

Nick you're BUSTED! I know your handwriting little dude!
