Strictly speaking, James didn't do so terribly well with being ignored. Apart from it being ridiculous-- well. No. It was just ridiculous. And there didn't need to be any other qualifiers than that. It was running away, it was burying his head in the sand, and it was just such a waste of time.
Just because it was stupid and childish, however, didn't mean that James wasn't perfectly capable of ignoring Regulus right back. It wasn't like he was going to go chasing after Regulus or anything. He was the one making the requisite gesture, and now he could say he'd given it a shot. If Regulus didn't want to talk about it, that was hardly his problem. Officially, the ball was in his court, and if Regulus had something to say, he could sort it out himself.
So fine.
After flicking away a bit of ash, James lifted his cigarette to his lips again. One of these days, Regulus was going to learn to not take everything so fucking seriously, and then hell would charmingly just freeze right over.
Come to think of it, James sort of missed the February snow. Actually. Just when the hell was it? Sirius thought it was October. For him, it was probably March or something. There had to be a calendar or something, somewhere, that would be inclined to tell him what the actual date was supposed to be. Maybe.
