Don't tell me the moon is shining; show me the glint of light on broken glass. 

Often attributed to Anton Chekhov, this line encapsulates a core realist principle: effective writing relies on concrete, sensory particulars rather than abstract assertions. “Don’t tell me” rejects authorial explanation (“the moon is shining”) in favor of an image that lets the reader infer the same fact through perception (“the glint of light on broken glass”). The broken glass also adds tonal complexity—beauty mixed with danger or poverty—suggesting how precise detail can carry mood, social texture, and subtext simultaneously. As a maxim, it is frequently used to teach “show, don’t tell,” emphasizing that vivid specifics create credibility and emotional resonance.

“Don’t tell me the moon is shining; show me the glint of light on broken glass.”
“Don’t tell me the moon is shining; show me the reflection of light on broken glass.”
“Don’t say the moon is shining; show me the glint of light on broken glass.”
