(I’m in an astronomy class taught by a teacher who works both at our school and the rival high school. The rival school has a planetarium but ours doesn’t, so we take a day-long field trip to the other school a couple times that year to use it. The rivalry between our schools is incredibly intense, especially around the football season, so we receive this warning from the astronomy teacher on the bus ride over.)
Teacher: “Okay, now, I want you all to listen up. When I brought my last class over it was right before the big football game. We arrived right at the change of classes, someone spotted our IDs, and I found myself nearly having to diffuse a riot. You guys are a much smaller class and will be vastly outnumbered. I want you all to hide your IDs. Do not take them out for anyone and do not let them know which school you come from!”
(As we arrive, a security guard waiting to check our IDs notices that we have them all pocketed.)
Security Guard: “School IDs out at all times, please. The policy is the same here as it is at your school.”
Teacher: “No, [Guard]! I told them to hide them so that we didn’t have another riot!”
(The security guard looks at him, then at us, and then gets this glazed over look on his face like he suddenly remembers something. He looks at the clock then back at us.)
Security Guard: “Classes are about to let out! The planetarium’s down that way! Quick, hide your IDs and run! Run! I’ll come check them once you’re all safe!”
(Admittedly that was the first time a security guard ever told us to run in the halls…)
