Transcript[]
Dear Uncle, it's been a while since I've heard from you. And with the way things are going, I can't be sure we will see each other again. I just wanted to tell you I'm doing well, and I'm safe for now. My job, caring for - a young girl, is better than I expected. But she can be very trying. But I'm treated well. There is enough to eat. I fare better than most, I suppose. We are the last of our family, Uncle Curnow. We just have to go on living. If we can. May we see each other soon, your niece, Callista.
