Chuckling, Ezra said, "Perhaps next week when I renew the ads, I will. Keen mustache, is it?" He toyed with one end of it and smiled at the compliment, though he was joking about actually including her number as a reference. For one thing, he didn't actually have it, and he wasn't about to ask for it, and for another-- well, that would probably be a bit strange, wouldn't it? Having a random person's number as a reference. Or maybe it wouldn't. He couldn't honestly say, though he hadn't seen such a thing before, himself.
Regardless, this was a charming child. "I may have to stop by your antique shop sometime, if you are going to compliment my mustache." He said it in such a joking manner that, he hoped, it wouldn't come off as creepy, just silly.
