Caitlyn has decided to determine the distance between home and school. So she counts to herself, "One, two, three, four..." starting, of course, at some random point along the bus route. When the bus stops, she stops. When the bus gets going again, she picks up where she left off. "Eighteen, nineteen, twenty, twenty-one..." She gets to thirty-nine before needing help.

"What comes after thirty-nine?"

"Forty."

"Forty. Forty-one, forty-two, forty-three..."

She made it to one hundred nine before getting snarled up in what should be next, asking me instead for what should come after ninety. Fortunately, it was our stop and we exited the bus. Caitlyn announced, "It's 98 to school!"
