'Dear Samuel,
How have you been? Have you been eating well? Do you sleep at all or not? I heard from General Yakov that you haven't been doing well enough. It's alright. Take it slow.
General Yakov sent me a picture of yours from New Year's. You have changed so much, I almost couldn't recognize you! He told me that you grew taller quickly, too. I can't wait to see you in real life.
I can't believe it's been 4 years, Samuel. I really can't believe it. Meeting you was probably the most unbelievable thing that occurred to me anyway.
And Samuel, write back to me, will you? You never write back to me. Remember that I'm the only one you can trust. I'm the only one you can lean on. I'm the only one you have!
