Sometime last year, we taught Arthur an alternative way to sing "The Wheels on the Bus." We have a picture book that has animals riding the bus, and for the verse where the bus hits a bump in the road, "The animals on the bus go up and down." We've added "The animals on the bus go 'ooph!' and 'ack!'" for the last iteration and that's Arthur's cue to shout, "I'll sue!"
So, what does he start shouting for no apparent reason that I can figure out at the reception desk of a doctor's office?
I leaned over him and said, "That's a bad thing to shout in a doctor's office before the appointment."
