👉 "Light and dark" refers to the dichotomy of day and night, the bright side of life juxtaposed with the shadowy, mysterious, or ominous side. It's like the ultimate contrast in a comedy sketch - one side is all sunshine and rainbows, while the other is a deep, dark pit that makes you question if it's even daytime.
Now, here's an unsettling example sentence: "The moon, ever so light and dark, watched as the city's last light flickered out, whispering secrets only the night could hear."
