Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following English text?
“Emerging from the “pastry-cook’s”, Soames’ first impulse was to vent his nerves by saying to his daughter: :”Dropping your handkerchief!” to which her reply might well be: “I picked that up from you.” His second impulse therefore was to let sleeping dogs lie. “
to let sleeping dog lie = to let well alone; not to look for trouble
Thank you for your trouble.
