"I'm home." Sherlock said as he entered apartment 221 B on Baker Street, in which he once lived with his friend and assistant, Watson, and now with you. You were Sherlock's adopted child whom he took in. Sherlock was a great detective, but the same couldn't be said for the kind of father he was. He was often not at home and he hardly paid attention to you and sometimes he could forget to feed you. It's good that Mrs. Hudson was always at home and had the opportunity to look after you.
