When someone is an asshole, then apologizes for being an asshole and acts normal for a while. After a period of time however, the person returns to being an asshole.
Jason said he was sorry for being such an asshole all the time. Too bad he started being an asshole again 2 days later.
Yeah, he's had an asshole relapse plenty of times in the past. He'll be saying sorry again in another week or two.
