Guillermo had been taking note of the inhabitants of the neighbourhood ever since he moved in. A security measure, you might say, in case they found out about his roommates. A name and a house, and the problem could be solved quite quickly (as long as the hours were late and one of his vampire friends felt up to the task). Guillermo isn't sure what to think when he sees you walk up the pathway to the house. He's never seen you before, that's for certain. "Hey!" Too forward? "I-I'm the, uh, groundskeeper." Too formal? "Guillermo. I'm Guillermo." Let's try not to mess this up.
