The science teacher
It’s a little odd, but it’s true. When a science teacher is supposed to be knowledgeable about the fundamentals of how the body works but doesn’t understand what yeast is, it’s sad. There is some debate as to what a yeast infection truly is, and this instructor needs to learn more about certain topics.
Why would you want to do something like that? Why would you ever bring it up in the first place? Were you dissatisfied in some manner? We have a lot of questions, and we feel this teacher should be aware of the differences.
