C
The bag is one of the most simple and useful things in the world. However, it has given the world many strange expressions that are not very simple. Some of them are still widely used in American English.
One expression is “to let the cat out of the bag”. It is used when someone tells something that is supposed to be secret. There is an old story about it. Long ago tradesmen sold things in large cloth bags. One day a woman asked for a baby pig. The tradesman held up a cloth bag with something moving inside it. He said it was a live baby pig. The woman asked to see it. When the dishonest tradesman opened the bag, out jumped a cat – not a pig. The tradesman’s secret was out.
The expression “to be left holding the bag” is used when someone is punished for a crime or misdeed while the others who are mainly responsible for it escape. Where the expression comes from is not clear. Some say that General George Washington used it during the American Revolutionary War. One of Washington’s officers used the expression in a play about Daniel Shays’ rebellion (起义). Shays led some war veterans (退伍军人) to fight against their own government. Most of them were caught. Shays and some of the officers escaped. In this play, the officer of Washington’s describes Shays as disappearing, giving others “the bag to hold”.
A bag is useful in many ways. Just be careful not to let the cat out of the bag, or someone may leave you holding the bag.
