Bucky didn't hesitate to join up the additional work in Wood Sector when the call came out. It didn't sit well with the rationing, but he's done work on not much food, before, and this is probably actually necessary.

And it's easier not to overthink what he can't change if he's got something to do, anyway.

Easier, but not easy. Especially with what need to be mending, Bucky's general mood turns to morose, when he has tasks to do on his own.
