Talk to the principal next time about where you are supposed to go. It’s not okay you were left out. What is there was an active shooter? There should be a plan for adults.
As a teacher, this is sad, but it is what it is with the state of things. School shootings are the norm now, no one likes it. I’ve actually been in one and we had to go into lock down with an active shooter. It was okay, no one got shot, but this is why we have drills.
People are dead set on their 2nd amendment rights, even if 5 year old children have to die for it.
