I think of all the times you held my hand (metaphorically, unfortunately) when I was first promoted, and all the times you posted chapters for me or helped me get through the tangled web that was our old software package. I often talk about how awesome my team is, but you were the secret member in the corner, the closet member, who made so much happen for me. I am truly grateful for all your work, and even more than that, for the pleasant and charming person that you are.
There are times when we have to move on to more important, or different things in life. I'm sad to see you uninvolve yourself here, but I totally understand why you're doing it. Best of luck, my friend.
