There are not hobby groups in the Russian schools (as opposed to Japan), so teenagers often spend their time how they want after the lessons. Sometimes all the friends go to somebody’s home or just hang out inside the entrance.
One more version – to get together in a place, which is not so comfortable, but without adults.
Very often such "secret shelter" become dacha – private house with farmland, which have many of Russia's family.
People, who live in the private sector, have a possibility to settle down in some deserted house or it can pass to them from elderly relatives.
In this "secret shelter" are kept such «treasures» as old weapons and food’s supplies (when Nika was taking out his food, he had noticed, that "there is only any rubbish", that is supply was bigger).
It’s a whole club in DtB2 – with computer and photoprinter, that is has electricity, so this house is not very neglected.
