What do you call the act of pretending to be someone else? Spies often pretend to be someone else. I was wondering if the word "performance" could be used to refer to the act of pretending spies often do? I am wondering if it's only used for stage actors.
The spy got lost in his performance and started believing the lies he put up to the public.
The spy got tired of his performance and decided to behave like himself, which he later regretted when he noticed someone trailing him.
