You give your younger sister Alex a call. She wishes you a happy birthday and says she would be delighted to come over to live with you. She doesn't say anything when you said to start a family with her. I guess that's a conversation for later.
Later that day, after informing your family of your change in fortune. Alex and you were planning your move, sorting out what stuff to keep and what to give away. Informing the extended family of their loss. Having the police inspect the building for signs of a struggle and finding none.
With plans in place and the bed freshly made Alex asks you
What now birthday boy?
