It's not necessary to rename the story, to my opinion. Besides, the story flow is an unpredictable thing. You can't know where it will go, and in the end in might be not a "Sanctuary" at all. So I'd say keep the original title.
I've read the entry you posted, it's good and promising, although very short. Will wait for the next chapter.

Sorry for the Double Post but here is Entry Three:

Sorry, couldn't reply before, I like that three parts very much, especially 2nd one touched me for some reason. Great work with details - lollypops, saxophone placed on the table instead of sweet & sour sauce, Lisa's worryings about did her mom read this writings, Bart's fake interest in sister, which she still likes - mood of your story is very simpsonic. And it's interesting and easy to read. I wonder, why you not supporting Lisa's Diary RR - I don't know much about your mistakes due to my bad english, but your plot is quite Simpsonic indeed. Keep it up, please!

Oh, just a little about nitpicks: I don't know, do Lisa call Mag and Bart "siblings"? In russian we rarely use this word, especially in informal communication, so for me it was weird a bit, but maybe it's just me. And I doubt that Marge could let Maggie play snowball fight with Bart and Homer. But however, it doesn't spoil your story.
