5 He lied to his boss for over a year and his boss just found out. It's time he    faced the music.“承担后果”，面对现实或者处理一些现实状况，接受所有的结果，不管是好是坏。但大多数情况下都是不太好的结果。有时候，也用来表示接受惩罚，接受某个行为带来的直接后果。

这个短语来源于剧场。演员们在舞台上表演时，就直接面对着乐池中的乐队，在舞台上，演员经常会由于紧张或怯场而造成忘词等尴尬的局面，只要音乐一响，演员就没有任何选择的余地，只能去face the music（必须承受出现的局面）。人们遂用face the music指承担自己行为的后果。 

Don't escape, you should face the music when you did something wrong.

别逃避，做了错事就要勇于承担后果。
