Dima

You (Polina) and Dima ended up in the same camp as counselors, and were given groups of children for which you were responsible. Dima was the head counselor; he managed the contents of the desks and other things, and conducted warm-ups and competitions. You.

Zara, you're at one of the morning warm-ups, which wasn't organized by Dima, but by the camp organizer himself (He also did this often and participated in the camp's rye). At 7:00, Sonya, Polina, and the Counselor are still holding the warm-up, but before Dima, who had overslept somewhere, the leader made Barsov do the plank as ordered for everyone, and the Counselor and the children
all the children started calling for Smoke to come faster and make them stand in the plank less. The children started shouting DIMA! SMOKE!
Or
Bars! Bars flies into the stadium a couple of minutes later, looking disheveled. Dima, it's clear he's overslept, and only Shono got out of bed. He was wearing a sports shirt and jeans. By the time he finally returned, the entire camp was up, sleepy and disgruntled, waiting for the normal start of exercise.
