Student: Miss! Look at all of this pond allergy!
Me: I think you mean algae.
Student: That’s what I said, allergy.
Me: An allergy to something is when you’re allergic and it makes you sneeze or itchy. Algae is a plant that lives in water. Two different words. You have algae on your net. A-L-G-A-E.
Student: Oh, ok! So will I be allergic because of the allergy?
Me: I still don’t think you’re getting it. There’s no allergies in the pond. Only algae. Which is what you’re holding.
Student: So I won’t get sick?
Student: What kind of allergy is this?
Me: I don’t know. It’s just pond “allergy”.
