I was thinking about the thin line between reality and fantasy for children when we were driving along and Cookie told this story:
"Mom, here is something that is a true story. I and Princess and you bought a Popcicle from an ice cream truck. And Gameboy wasn't born yet."
That would be her older brother who wasn't born yet in this story. She paused for a moment, then said:
"Oh, wait a second. Maybe that was a dream."
She shook her head as if to rattle out the truth, but then gave up and, I would imagine, just started thinking about ice cream and Popcicles instead.
