Harmony

AJ has a passion for music and is a big fan of Broadway...

On the way home one evening, AJ was singing happily to himself in the car.

I remarked, "That's a nice song."

He very clearly replied, "Harmony."

Amused and amazed, I asked, "What's harmony?"

He immediately replied, "A duet."

Next time they need a sub for the music teacher at school, maybe he can fill in…
