"Are you sure we should do this?" Rachel asked, turning to me.

"Yup."

"I just don't know if I want to do this to my brother!"

"Look, we all gotta make sacrifices. And someone's gotta do something about that out-of-control piano teacher!"

"Well, OK."

"Look, here he comes."

We watched as Harvey McKenzie stepped up to the piano teacher's front door. She welcomed him inside.

"How long does it usually take before….kaboom?" I asked, referring to one of Harvey's full-on don't-touch-me freakouts.

"Two or three touches," Rachel pointed out.

Five minutes later, the house practically exploded.

"DO NOT! EVER! TOUCH ME! EVER! EVER!"

My ex-piano teacher was last seen running for the hills.

I laughed and high-fived Rachel, then turned to the door that Harvey was coming out of, stopped, and put my hand down.

"Good job."

"You could've at least let me in on the plan," he grouched.

"Yea, but where's the fun in that?" I slid.

We burst out laughing.
