Dear Mark,

Mark, if you're seeing this, (which I'd seriously doubt) this is just a little something I've been wanting to tell you. No, it's not one of those "I'm in love with you!" things. It's more like: Thank you for what you've done for me. You've done so much, changing and saving my life. So enough of this description, it's the actual story that is important.
Thank you. So much.
