Father: Can't you just try sharing a room with your sister? Your mom was always so good at this stuff. I'd come home from work and everything was always perfect. How would mom have handled this?

Father: What is it honey?
Daughter: It is just not fair. First, I lose my mom! Then grandma leaves. Now even I lose my own room.
Father: I know how much you girls miss your mother. Because I miss her too. Very much. But you still got me.
