"What!" The Doctor looked at the man appalled, "you honestly think I would proffer a dirty hand in embrace to a new friend? That would be terrible manners, not to mention awfully unhygienic!" Though, to be fair, he'd had his hands in places most people didn't know existed, and that was just when he was in public! "Not a title - common mistake - it's a name. The. Doctor, though you can call me Doctor, should you find yourself in need of fewer syllables." Well that was a lot easier than it normally was, he grinned, pleased with the ease with which his roommate picked things up. "That's right, though no green puss or googly eyes here, just me and my two hearts."
He looked at Hal Yorke with a new respect, "so you're a vampire! How exciting. Haven't met a vampire in...oooh, years! What sort? The common-or-garden blood-sucking sort, or a psychic emotion-stealing vampire? Just curious. Don't worry, I'm an equal opportunities communicator," The Doctor told him happily. "Ooh, you've met werewolves? How exciting! I haven't met a werewolf since I was with Queen Victoria. That was quite an adventure, as I'm sure you'd appreciate!" There were very few things that would stop The Doctor in his tracks, but having a vampire roommate suggest rules for living by was definitely one of them. "You mean like a washing up rota?" he asked curiously. "Do you even do washing up? I mean, it's not like your preferred food actually needs a bowl! You might as well skip that stage all together," he suggested happily. "What kind of rules would you like... though I should warn you, I'm not very good with rules. I tend to break them. Often. It's what you might call a personality flaw."
