The history teacher was reading his textbook, walking between the desks. You grimace in disgust when you notice that his crotch is very close to your arm.

Ian Gallagher has been sitting behind you for three years, sometimes he says things that make you laugh or you feel him pulling your hair gently when you joke with him.

When the disgusting old man resumed his walk, he fell to the ground. Ian's backpack was in the middle of the road. He had a side smile, satisfied with his work.
