1. Amos respects that she's busy and won't argue his points further (the whole "don't force it on them" thing is non-negotiable for him, anyway, so that tinges how he sees her now, for however much that introspection is worth).

He's pretty indifferent to her first response, but the second will make him pause, though he still won't commit (see: the whole non-negotiable stance). Just a little seedling of doubt he'll ignore until it's relevant again.

2. Aww. He totally gets just wanting to get through the day and is unlikely to pick up on that edge of anxiety in any way that matters (i.e. if expressed towards him he may stop with a blank look before shrugging and going back to what he's doing — it's the kind of thing he's used to, albeit he doesn't really know why that's happening here).

(And thank you for these!)
