Aha, I remember this one because I had to help you fill out your papers, remember? The old lady who'd been taking care of you, you called her the CatLady? Her name was Sharon. It was on some papers they found there when Animal Control picked you up, and so that's what got used when we had to put together human-type identification for you. "Smith" got picked as a random last name before we knew it was actually your real one.
