So Bucky can sneak up on basically anyone because he was, you know, an assassin, and sneaking tends to be a skill assassins need. But for some reason, Steve always knows he’s there, and it drives him absolutely insane. 

On more than one occasion, Steve’s been sitting at his desk drawing or writing emails or whatever for a while, and Bucky thinks, okay, this is my chance. So he opens the door and eases into the room. Silently. He stands there for a while, and Steve doesn’t say anything. And just as he’s starting to thing that this is it, it’s been fifteen minutes and Steve clearly has no idea, Steve will say something like “I was thinking of ordering in for dinner today, what do you think?” and Bucky wants to hit something.
