When I was in high school, I took an entomology class. As part of this class, I caught insects and pinned them to boards. I learned about the scientific names for different insects. I learned how to categorize insects. I learned that there are dragonflies and there are damselflies.
My teacher somehow acquired a pig corpse. If memory serves me correctly (it might not), she got the pig already dead from a friend and the pig had a tumor. I’m not sure that these details are true.
Anyway, she got a pig corpse. What did she do with the pig corpse? Let it rot on school grounds, of course! It smelled horrible. It also attracted lots of insects. I caught many types of flies. I think there were maggots too.
In retrospect, I don’t think other people had this kind of experience in high school.
