Rant and Rave

I was wondering why I found the two people rehearsing their ballroom dancing in front of the music library so irritating. It was not just that they were bad, but they were arrogant as well. Rehearsing in public means the public has a right to be entertained. But these two obviously only care about impressing teachers or a class. Basically they are not doing it for the right reasons. Not in my mind.
