My service dog

Twice recently, I have called Fame by the name of my first service dog Claren.

When it first happened -- I told Mom to grab me Claren's toothbrush -- Mom suggested it was because it was near t he anniversary of Claren's death. But it happened later, with a friend at work.

In my head, I have been calling Fame Claren since before we graduated.  I told one of the trainers that she must be working out well because I am calling her by her predecessor's name. The trainer said that was normal.

I don't get why it is happening now.
