Rodney happened to be walking by when he saw the little girl. He regretted instantly taking this route because now it seemed like he was going to have to engage with this child. He looked around a few more times to determine if there was an adult watching her, even from a window or something, but it seemed like there wasn't. McKay's lips pressed into an unhappy frown. This girl looked to be the same age as his niece. Probably, anyways - Little children all looked the same to the neurotic scientist.
He cleared his throat as he slowly approached. "Um. Excuse me. Little girl?" Rodney noticed it looked like she was wearing pajamas. Where were her parents and how could they let this happen?! "Shouldn't you be inside watching cartoons or something?"
