Edward,
Lately, you seem angrier than normal. You're well known about the office now for your temper, but this is different. I wish I didn't, but I think I know why.
When we first met, you might have been called petulant (underneath the exterior trauma, that is). But I don't think you disliked me; at least, I would hope that wasn't the case. And yet now I sense a distinct animosity from you. I don't have to be a genius to figure out that you're upset when I have to send you off on a task that doesn't directly relate to your own goals.
It's just my job, as it is yours to follow my orders. Obviously, though, you have been taking that personally.
I knew it would be hard for you to grasp the concept of being a dog of the military. Even now, what you are being made to do is minor, merely a scratch on the surface of what us dogs have been forced into before. Though I am not a religious man, I pray you never have to be used as that sort of weapon.
Patience is all you need. Distractions are inconvenient, yes, but you have not been derailed by any means from your path. Patience is a virtue, and a learned one at that. I can only hope you learn it soon; the constant arguing is exhausting. Frankly, I think I would enjoy your company more if you were to keep just a little quieter.
One really must choose their battles. You seem to be choosing all of them; if that energy weren't directed at me, I daresay I'd be delighted by such tenacity. As it is…give me a break, Fullmetal. I am doing all that I can for the big picture. You and your brother are included in that. I just wish you would have faith.
Signed,
Colonel Roy Mustang
