Dear John,

I'm sorry. Those are the words you're waiting for, right? I don't regret doing what I did, but I know it hurt you - and that, I truly am sorry for. Please, let me explain. Don't throw away everything we had before and everything we built together while I was gone. Call me? I tried your old number - the one you gave me in December - but my texts wouldn't go through.

- Sherlock
