School girl cuffed to the black board

Aubrey is in detention! She hates school, but she will have to stay for a few extra hours. She is told to go to the black board and neck cuff herself to it. The long chain allows her to do assigments on the board, and she will be released when she finishes her work. But she doesn’t seem to be very motivated to do so. She scribbles a bit and then sits down. School sucks!
