My son has written four letters since he left for basic training ten days ago. He has always loved to write, so it doesn't surprise me. I'll probably get a letter every couple of days, whereas I think I got two letters total from the oldest one.
He's safe and he's happy and he (so far) loves the Army. I've also had a phone call, and I asked him, "Do you like it?" He said he did. I asked, "Do you love it?" His answer: "Most definitely."
So, he's doing something that he loves. What more can you ask?
