Goffman called this frontstage and backstage.

戈夫曼称之为前台和后台。

Often the things we do backstage would totally ruin the performance we're trying to maintain frontstage.

通常我们在后台所做的事情会完全破坏我们试图在前台保持的性能。

Frontstage is where the audience is and where the performance happens, while backstage is where the performer can drop the performance and prepare.

前台是观众所在的地方，也是表演发生的地方，而后台是表演者放下表演准备的地方。
