sleeping

let sleeping dogs lie avoid interfering in a situation that is currently causing no problems, but may well do so as a consequence of such interference. proverb

☞ In the early 14th century the French phrase n'esveillez pas lou chien qui dort advised 'do not wake the sleeping dog', while Chaucer remarks in Troilus and Criseyde 'it is nought good a slepyng hound to wake'. The present form of the proverb seems to be traceable to Walter Scott's novel Redgauntlet (1824).
