Only cinema or TV actors don’t do acting, but general people also do. Like, in front of your boss you show that you really honor him, respect him…but with other person you always say that your boss know nothing. In front of your wife, you show that you love her a lot… but in front of other beautiful women you say you don’t love your wife at all. In front of your son you show you care for your daughter in law and her kid a lot. But unless your son came from office, you show hate to them in every single way.
I think, general people know, how to perform, more that an actor, to achieve their goal.
