In the evenings, the counselor went around her property and checked that there were 7 people in the rooms on each side of the building. Once, four guys from a neighboring building came to visit the first squad and stayed overnight. Moreover, 24 children were accommodated in such a way that in the evening the counselor counted 7 people again in the rooms on each side of the building.

The next day, four desperate people ran away to swim on the river and did not spend the night in the building. The remaining 16 guys were accommodated so that in the evening the counselor again counted 7 people in the rooms on each side of the building.
