Steve makes a face at the oven, so at least B can't see it. "Yeah, I know."

Yes, he's aware it makes him sound like a belligerent child. It's not like he never expects to have shitty days. This just... feels like a massive failure on his part, so it's only fair that he feels bad.

Maybe it's just that he's all too aware: "It woulda been different. Before."

He would've been different. Before everything. He would've been better at handling that. At contributing.
