Projector Video explanation:

Callie Covets is paying more attention to the projector Professor Victor Visual is using in class rather than his lecture. Professor Victor Visual calls on Callie to answer a question but notices that Callie Covets is not paying any attention to his lecture and more on the projector. Professor Visual explains to Callie he promises to give Callie the projector at the end of class if she stops eyeing the projector and listens to his lecture more. Callie agrees but then runs out of class without any notice. Once class is over Callie comes back to Professor Visual's class to get the projector he promised her at the end of class. Professor Visual changes his mind and realizes the projector is very special to him and he just can't give it away.
