A、He’s late for social occasions but not for work. B、He’s a quiet person but likes to make grand entrances. C、He expects others

W: Mark really needs to see this article in Psychology Weekly.
M: Why? What’s it on?
W: Reasons for negative behavior patterns—like procrastination, that is, habitual lateness...
M: You’re right. That’s Mark. He’s never on time. So what does it say?
W: That people who are always late often do it for a reason—either conscious or unconscious. It could be an expression of anger and resentment—or a way of resisting authority. It could even be anxiety.
M: Well, I don’t know. In Mark’s case, I think it’s because he wants to be noticed.
W: That’s the next reason in the article—the need for attention. They give the example of movie stars who used to make these grand entrances.
M: That’s not really Mark’s style though—he’s so quiet.
W: What gets me is that [21]he’s late for his friends all the time—but not for other things, like work.
M: Well... but they might deduct pay for that.
W: Exactly. You know, sometimes I’m tempted to tell him to come at, say, seven, and everybody else at 7:15. Then maybe we wouldn’t have to wait so long.
M: We have to try something. You know, he confessed to me one day that he was even late for his sister’s wedding. She was really angry.
W: I remember that. He was not in the wedding—so they couldn’t start until he got there.
M: Maybe you should slip that magazine under his door—anonymously. And hope he gets the message.
