is my MBA bent?

Hey.

When I pick up my 2012 MBA, I sometimes hear a sound and feel that something seems to be loose. First I thought, the screws might have come loose but that doesn't seem to be the case.

I will let this video speak for itself:

Does anybody else have this behavior? My Macbook never fell down or something like that. I think there should be no gap between the rubber rim around the display and the chassis when it is closed.
