Idioms

Chad, my oral teacher, asked us to find some idioms and write them down last week. I fund some idioms on internet, for example, to pull someone's leg means to make joke to someone. And you are an apple of my eye means that I like you very much. One of idioms what Chad taught made me impressed is breaking a leg. The idiom, break a leg, derives from a story. In the end of performance, performers will appreciate audience with their knees bent. And they have to keep the action until audience stop clapping. Sometimes, they did a very nice performance and audience clapped for 10 minutes even. There were aches in their knees as if their leg was broke. Therefore, breaking a leg means to do a good job or good luck.
