I took my two daughters, Abby and Flannery, out to get something fun to drink at a coffee stand. Abby got an apple juice, and Flannery got a mango surprise. Despite my insistence that I would pay, my daughters had brought the contents of their piggy banks, a combined total of about 80 cents.

As we were walking up to the counter, one of them said, "I want to pay for mine."

I assured her, "Daddy's gonna get it."

Nonetheless, she insisted, "I'm paying for mine."

As the clerk rang it up, he said, "That'll be $2.06," and she put her change on the counter. "Um, that's… that's not enough," the clerk responded.

I felt a little tug at my sweater from my other daughter. I looked down, and she said, "I think I'd like to use your money."
