One time when I was a kid, we went on a long car trip and a thunderstorm approached. My dad said, "Don't worry about the sound. It's the light that kills you!" My Japanese mom was not cool with this. "No, it's the sound. What are you talking about?" A fierce argument ensued.
So, the words for thunder and lightning in Japanese are kaminari and inazuma, respectively. But that's not a perfect translation. kaminari means something like "peal of the gods", and is the forceful, dangerous part. inazuma is basically just a light show.
English is the opposite. Thunder is just a sound, while lightning can kill you. To put it another way, in English, one word is light + electricity while the other is sound. In Japanese, one word is sound + electricity while the other is light.
Anyway, I was about to speak up when my big brother tugged my arm. "No. This is a popcorn moment. Don't ruin it!"
