On my way into the library today, two boys were walking out. Little boys. One of them had his hand cupped to his ear and was exclaiming, "I can hear the choo choo! I can hear it!" He mounted the steps and as his little head came up over the crest of the staircase, he cried, "I can see it too! I can see the train!"
His mom, bless her heart, said, "You can see the choo choo? No, I don't think you can."
And that's how little boys forget how to fly.
