In my junior year, it was nearing the end of lunch. I was sitting in my usual spot with friends when suddenly we hear screaming and see everyone running from the staircase, which was the most crowded spot during lunch.
Didn't really think much of it at first, but then an announcement started going off, telling everyone to go to back to their last class. I couldn't hear the announcement over the commotion, so I asked someone in the office what was going on and they told me we were under code red and that I had to go to my NEXT class.
So I made my way quickly to my 6th period classroom. The door was locked so I knocked. My teacher looked over at me, but didn't come over for several minutes. Mind you, I was pretty scared lol alarms were going off and people were running to their classrooms.
My teacher opened the door a crack, not allowing me to come through and asked what I was doing. I told him I was told to come to my next class. He simply said "no, you have to go back to your 5th period" and shut the door.
My 5th period was on the other campus (it was a huge high school), a good 10 minute walk through the parking lot.
I started getting anxiety as I made my way to my 5th period. This was the first year I had ever attended public school and I had never experienced anything like this. The school was so quiet, nobody was around because everyone had already ran to their classrooms. I'm on the verge of tears when I see a teacher locking up her classroom door. She sees me and asks where I'm going, and I tell her my 5th period is on the other campus. She ushered me in and told me that I can't walk that far, we were under lockdown and it would take me too long to get there.
I was so relieved she let me in. I later learned that someone had brought a gun into the school and was waving it around during lunch, and they had to lockdown everything because it went missing apparently.
