Patient, Loyal Friend

Every evening Emily spends some time lying on the chest of drawers in the corner of the living room, waiting for her sister Midnight to appear again.  It's easy to see the pain and sadness in her eyes.  Her heart is broken as well as mine.   I wish I could change it for us.  Instead of going off to sleep by herself, most of the time now Emily sleeps at or on my feet.  Is she afraid that I'll disappear too?  I'm glad she has another sister cat here, but it's clear she doesn't take Midnight's place.
