after watching the video, i think i have to agree with all or nothin - we see him throwin around a bunch of stuff at his apartment but none of it hits the ground and then he walks out and then when the girl walks in, all the stuff that had been hovering in midair comes crashing down and a tear falls from her eye. so i think all the stuff crashing is to emphasize just how much it hurt him when she broke up with him or something like that and to show that he's sooo done with her now, and she realizes that and that's why she's crying.
