"I know I... haven't been at my best. And I'm sorry about that." It's genuine, not a pointless placation. He hasn't been doing too well at watching what he says lately, and he knows it.

Yep, totally normal and fine... and it may seem a whole lot like he actually thinks that, probably because he does.
