I had an ulterior motive for getting us out of the apartment, beyond providing cover for Sam with Mom and Dad, beyond getting groceries so that we could spend as much time in whatever shared depravity we chose. We needed to make sure that this new normal really could be at least outwardly normal. We might be going back home to fuck each others' brains out later, but we had to keep up the pretense of being just a brother and sister when we were out in public.
