jeff the killer's twin sister

so hi I'm Jeffreys twin sister named Lillian I'm 17 just like Jeffrey, my b-day is Dec 25. but when I was three I got adopted to another family but my real parents kept jeffrey, I'm guessing they thought that money would be easier. my family now is a very good family they are rich and live in Beverley hills. I'm mostly home alone with my brother Stephan who is 18 -well I guess onto the story-
