Leonard spends so much time trying to make everything go right on the job that it's a behavior that often leaks into every day things, too. He can't help it, he isn't sure he could stop it if he tried. But it's a point of contention between him and Mick, often.

It's the sort of fight that's just cyclic in nature and happens over and over, that they can't escape. Apparently, it's happening again. He's over-stepped too far and Mick didn't take so well to it.

"Oh, fuck off," He barely even sounds more than marginally annoyed, personally. "You knew what you were signing on for years ago, Mick. This is hardly new." he rolls his eyes.
