તારી નિશાળે કાઈ ભણ્યું નથી.

tārī niśāḷē kāī bhaṇyuṁ nathī.

Literally: No one has studied at your school.
What it means: Said to dismiss someone's attempts to teach, trick, or advise, implying their methods are completely ineffective.

Also said as

ગુજરાતી કહેવતસંગ્રહ (Gujarati Kahevat Sangrah) (1923) · read from the scan by machine — the Gujarati itself is unchecked · English is machine-made and nobody has checked it yet

Heard it differently, or know we've got the sense wrong? Tell us — that is exactly the kind of correction this needs.
