I can fly but have no wings. I can cry but I have no eyes. Wherever I go, darkness follows me. What am I?

Why this works

This riddle plays on the descriptive qualities of clouds using metaphorical language. "I can fly but have no wings" refers to how clouds float in the sky, appearing to move freely without needing wings. The phrase "I can cry but I have no eyes" alludes to rain, as clouds release water but obviously lack eyes to cry with. Finally, "wherever I go, darkness follows me" highlights how clouds can block sunlight, creating shadows and darkness beneath them. Thus, the answer, clouds, perfectly encapsulates all these characteristics!
