Prank number 28 Backwards or Sideways

Idea: Have a student keep complaining that everything that they see is backwards, sideways and upside down.

Christina kept complaining that everything that she sees is backwards, sideways and upside down. It makes it hard to read the instructions on the blackboard. She told this to Professor Snape several times one day in potion's class.

Snape aloud: "There is an answer for that problem. All I would have to do is to blindfold you, and then you would not be able to see anything at all. I do not want to hear anymore about it either."

Snape thinking: Could there be an actual problem with Miss Clow's eyes. I will suggest that she should see Madame Pomfrey about her condition. Or could it be another prank being pulled on me. I think that I will say nothing at all.
