The cicadas have returned! Cicadas aren't really very scary unless you've never seen one...
One of our neighbors moved to Texas from Canada and one day we were outside chatting and she asked me, "What's that noise?"
I asked, "What noise?"
She said, "The noise in the air."
I listened a while and said, "I don't hear anything."
She insisted there was a noise in the air like a generator or something. I finally realized she was hearing the cicadas. I was so used to hearing their constant song, I didn't hear them anymore. I told her the noise was from cicadas. She asked what a cicada was. While I was unsuccessfully trying to describe them, one flew out of our tree and dived right at her.
She screamed louder than one of Freddy Kruger's victims and ran. I caught up with her and told her (after I'd managed to quit laughing), "That's a cicada."
