Role Reversal

As Booboo and I were sitting in the car waiting for the bus the other morning I had her help me clean all the garbage out of the car. I picked up a roudn cardboard canister out of the backseat and asked Booboo what it was. "It's mine Mom. Don't open it, ok?" 'Well what is it?" I asked. "What's inside?" "Don't worry about it Mom, just don't open it."
She crawled into the back seat and continued to clean out the car.
"What is inside this thing?" I asked, my curiosity peeking.
"Don't open it Mom, it's mine." said Booboo.
I couldn't help it, I wanted to know what was inside. While she wasn't looking I pulled and pulled and finally got the little canister open. Baby powder exploded out all over my face and clothes just as Booboo peeked back over the front seat.
"You just had to open it, didn't you Mom? I told you not to!" she said.
"Well you wouldn't tell me what was inside!" I exclaimed in self defence.
"It shouldn't matter." said Booboo, "it's mine and I asked you not to open it... Hey Mom?"
"What?" I asked as I tried shaking the powder off my t-shirt.
"Next time use your listening ears, not your hearing ears." she said with a smirk.
"Noted." I said with a laugh. She totally got me.
