Dear Sherlock,
I know that you are probably still cross with me for leaving, I'd be cross with me too. But it will only be one more year. One more year until we can see each other again. Training is hard, but it's alright because I know it will help me to save people. God, I hope I save people. Just thinking about being on the front lines makes my stomach hurt. I keep a picture of you in my pocket always. You don't have to respond to this letter. I understand if you don't. I love you.
Love,
John
