You're Special (Undiscovered Wattys 2014 Runner Up)

Aaron laughed, reminding me of his presence. He plopped down on the couch and patted his legs. "Come here, kiddo," he told Jamie.

Jamie looked at him, as if assessing a stranger. He stood up and put his hands on his hips, trying to be intimidating, but the effect was ruined because he stood up on the bean bag, which sagged under his weight and he fell down. Oh, but a little tripping wouldn't stop him. He stood back up, one eyebrow raised and arms crossed across his chest. "Now listen to me, Mister-" he began.
"Actually," Aaron interjected. "I'm a doctor."

Jamie held up a finger. "Don't ever again call me 'kiddo'. It's what you call kids. I'm 4 years young."
