“That’s nice,” he replied to his son, turning the page of his book. “Let me know when.”

He began to rethink the amount of attention he had given his son when he didn’t see him again for a week. When his son showed up again, he was ecstatic. “How about now?”

The father looked him over, considering. “Please don’t tell me it’s moving forward in real time. You washed that shirt since you last wore it, didn’t you?”

His son rolled his eyes, grabbed his father’s hand, and dragged him to the future.
