The context of the following conversation is Robin couldn't see from the back of the class. So Robin got closer to her teacher.:
Robin says I moved up front during class today and felt a little uncomfortable..
The friend responds Why?.
Robin responds I couldn't hear the instructor so I got up to move and then I got worried I'd disturb people..
The friend responds But you moved up?.
Robin responds Yes, it was too late to change my mind. And it helped!.
The friend responds Then don't worry about it. I am sure no one minded..
