It was Friday, on bus 1014, everyone was sweaty because everyone on the bus has gym last period, so the bus was very hot. He is a sixth grader sitting in the front of the bus, and all of the sudden, he starts shaking violently and gurgling, nobody noticed until about 1 minute after it started and another sixth grader told the bus driver. Me and the rest of the eighth graders were sitting in the back, so we didn't notice any of this until the bus stopped. Everyone sitting around me called 911, as did I, and the police, ambulance, and the fire department came. We were then loaded onto another bus, 912, and taken home, but first the principal came and told us that he would probably be okay.
tl;dr, friday, a 6th grader had a seizure, read the rest of the topic.
EDIT: He's OK, asablief.
