When someone leaves without saying goodbye, we use the express | LOST HISTORY

When someone leaves without saying goodbye, we use the expression "left in English”

Although the original idiom was coined by the British themselves, it sounded like 'to take French leave'. It appeared during the Seven Years' War in the 18th century as a mockery of French soldiers who were AWOL.

At that time the French copied the expression, but already in relation to the British, and in this form it stuck in the Russian language.
