[He grins, now, aiming for that "aw shucks" smile that Steve always had nailed, a little apologetic and grateful all at once as Art looks at him finally. Bucky squeezes his hand lightly.]
I woulda told you, I just... didn't wanna cause you more worry. [Not when you already had plenty, at the time. The remark about the dancing, though, that brings the grin back, as Bucky raises an eyebrow, his tone still light and teasing back, hoping for that tenseness to disappear soon-- they really need a break from all that... and focusing on his injury and the might-have-beens as he knows must be on Art's mind (because he knows they would be on his, were the situation reversed) won't do anything to help that.]
No, you can't- but what you can fault is I seem to recall not gettin' to dance with you, at all. Guess that's one more regret to add to the list.
