Hah, I had a similar experience yesterday with people who had no idea about cicadas! I caught a beautiful cicada in the grass and was holding it perched on my finger while I fumbled for my camera to take a picture. The people I was with had no idea what a cicada was, and when I explained that they’re the source of that daytime buzzing we hear in the trees this time of year, one said she had been wondering what bird makes that noise. The other said she had never noticed the noise until I pointed it out. Don’t people ever go outside?
(At least they admired the cicada, which sat placidly on my finger for a while.)
