My college used to be near a cerebral palsy center and one day I was walking by on the way to class while a lot of the patients were being helped onto school buses for what looked liked a coordinated field trip or something . I wasn ' t paying much attention other than just making sure I wasn ' t bumping into other pedestrians as I was deep in thought about exams and whatnot . At one point , I sort of made a weird face thinking about a possible route I would take with some project and quickly dismissing it as a stupid idea . As I ' m passing the bus , I hear one of the patients let out a frustrated scream and the nurse helping him asked what was wrong . He ' s making fun of me and thinks I ' m different , replied the patient . Absolutely broke my heart that this guy thought I was making fun of him . Ruined a larger part of my own day by not keeping in check my own facial expressions .
