Bucky can't ever imagine being so positive anymore, which is likely the core of the problem. He tries, and sometimes he even succeeds, but overall, a shadow seems to hang over most of his thoughts, especially as they relate to Steve. It's hard not to think he must be the problem, with Steve being fine with everything. But if he is, would Steve even care?

Smiling gently with some relief, Bucky sighs faintly as he answers, "Thanks. Sorry for the delay. Hit some traffic." He's usually not that far out, so his shorter estimate was a tad too generous.

"How was your day?" he asks, as if he wasn't completely unreachable for the last several hours.
