It's a usu weekday evening. You drink tea while eating a sandwich with raspberry jam and butter. Suddenly, you hear a knock on the door. You didn’t even have time to react when the door opened on its own, or rather, it was opened by the one who knocked.

— Hello, it’s me – Postman Pechkin. I brought a parcel for you. — Hello, well, where can I sign for receipt? – you said, taking a pen. — I brought a parcel for you, but I won’t give it to you, because you don’t have docÚments. - said the postman, straightening his mustache. —...But why did you bring the parcel here then? — And that’s the way it’s supposed to be, according to the rules, to bring the parcel to the recipient. Due to a rule I will come to you every day until you complete the documents at the local post office. – the postman said mockingly and slyly.
