Our school has been invaded by poisonous snakes. I just watched a 6th grade teacher kill one who was hiding in the small, dark space next to the water dispenser. Students like to cram themselves into this spot in order to ambush one another in water fights. My coteacher just told me to "be careful of snakes. There are many in the school. They will bite you, then you die."
I'm really happy that my only protection against these snakes is a verbal warning. Also that no one is doing anything to protect the children who roam unsupervised all over the school.
