"Be nice," Adam scolded, trying hard not to laugh. "Other people can chase these things, too, you know."
Shaking his head, he flashed the other guy a smile. "Ignore Little Miss Grumpypants, there. She gets a little bit... focused sometimes. Overly so. Don't mind her." A shrug. "Wouldn't have her any other way, though."
He grinned. "I'm Adam, by the way. Adam Milligan. And that little bundle of grump and annoy is my daughter Katie." He would never not find her concentration adorable, though.
