I think that Lauren is the girl next door because she's the type of girl that would appear to be the good little neighbor girl that everybody loves. But really is a wild party girl that loves to get into trouble and shoplift when no ones looking.
I voted Marshall because I think of the boy next door as someone you don't ever think of romantically and he's kinda sweet and innocent. Will could also be the boy next door. Maybe Dixon too. I WISH that Sark was the boy next door to me. That would be fun.
