Something Fishy With Her Reasoning

(I’m lucky enough to have a large garden and keep chickens and ducks as pets. I give away their excess eggs. I’m due to make a trip and visit my grandmother, so I call to see if she wants me to bring anything and offer her some eggs.)

Me: “Six chicken and six ducks eggs, or would you like more?”

Grandmother: *makes a slight “ack” noise* “Just chicken eggs; duck eggs are fishy.”

Me: “What do you mean, ‘fishy’? Duck eggs are very similar to chicken eggs, just a bit bigger and richer.”

Grandmother: “You know, fishy. They live on ponds…”

Me: “Nan, you have seen my garden. My ducks eat the same as the chickens and swim in a pool filled by a hose; there are no fish involved.”

Grandmother: “No, thank you. I just couldn’t eat fishy eggs.”
