problem fixed with object owned

I could convince my teacher that I had something wrong with my eyes and that the light bothered them really bad. I could then convince her I needed to keep my sunglasses on. My sunglasses have mirror lenses and you cannot see through them. I could write or tape cheat notes to the inside of the glasses and just make sure I could peek out the bottom of the glasses or make sure there was a small area I could see out of. This is how I could fix my problem, not doing good in one of my classes, with the object I own, sunglasses. BUT I would never do this!
