What does Ecclesiastes 7:6 mean?

Laughing fools are like the crackling of burning thorns under a pot—loud for a moment, but gone in a flash. That’s what chasing after pleasure is like: it’s empty. Ecclesiastes 7:6 - Modern Text Bible

(This verse compares shallow laughter to the quick, noisy burning of thorns—brief and meaningless. It’s a warning about the emptiness of foolish fun.)
