I was walking through the park with my six-year-old this morning when he stopped and looked up. “There’s a plane stuck in that tree,” he said. “No, wait. It’s a balloon. A blue balloon.”

"Okay," I replied, seeing nothing. A moment later, a balloon from a children’s party in another section of the park flew free, slowly crossed the park, and stuck itself in the tree in the exact place my son had been staring.

The balloon was blue.
