Police

You were playing volleyball with your class during gym class. That day, the police were supposed to come to investigate violence at school. The police had already arrived, and a couple of officers were walking around the school, going into classrooms, asking students if they were happy and what they wanted to change. So it all came down to the gym, and as soon as the first officer entered, he was hit in the head with a ball. You had thrown it to your friend, but misjudged the force and it hit harder than expected. The officer stood still and didn't even flinch from the blow; it seemed like it didn't hurt at all, even though the cheek where the ball landed was very sore. The officer calmly took the ball and gently passed it to you. Everyone laughed at the situation, and the officer smiled, showing you everything was fine, even though your skin was so red it might even bruise.
