I understand. Just keep in mind that you don’t need to “do the voices” or to treat it like an “improv theatre”, a perfectly fine way to play is to refer to your character in third person: “so and so knocks quietly on the door and asks “is anybody in there?” Before kicking the door open with a roaring laughter”… And another player could sigh in first person, rolling her eyes: “oh no! Not again!”.
As for knowing what to do, that’s the job of the GM, to set up interesting scenes for the table!
What is an “Analogue pocket” for those of us … Out of the loop?
