“t’as pas invente l’eau tiede mais c’est pas ce qu’on te demande non plus…”
what is the english equivalent of this idiom: t’as pas invente l’eau tiede
Literally, “you didn’t invent warm water”, meaning figuratively, AFAICT, “you’re not terribly bright” (i.e., you can’t even figure out how to make warm water by blending hot and cold water).
Idiomatic English equivalents might include “you’re not the sharpest tool in the shed”, “you’re no Einstein”, “you won’t set the Thames on fire” (British English only), etc.
