Temat przeniesiony do archwium.
Hello,

Could you tell me what past I should use to tell sb an imaginary story ? Let's say that I'm talking to sb and I want him to see some situation in his mind.
Present contiunous ? For example: Imgaine that there's a guy, sitting on the couch, he's watching TV...
moze byc present continuous
