And I was overwhelmed by hanging young offspring in a class by hour, with smartphones (this is not permissible, because another five people are dancing a tick under the door of the sort/soul.

And then I decided authoritatively - to enter the sort of onli without a smartphone. And so that it wasn’t boring, and for the sake of courage, I printed an A4 sheet with 10 interesting facts about the human body, and a scotch glued it in front of the toilet. By the evening, all the residents, including my five-year-old child, lively discussed the length of the intestines, the area of the skin, and the rate of cell renewal.

Then I had to update the infotainment. A list of records of the world of animals. By evening, the results of self-education are available. and carried.

And a week later I came to mind a brilliant idea - to hang a table of multiplication in the sorting. It should be said that her nephews taught her unreasonably.

The phenomenon of air refresher. Verified and works.
