The partition in the tent could have been there only if the girls wanted to change their clothes and underwear. But the question remains: if part of the sheet was sticking out, where did they hang it? There were two girls, so a relatively small section of the tent needed to be partitioned off so they could change. But the idea of changing clothes and a curtain dividing the tent into "men's" and "women's" doesn't fit with the discovery of the uncollected lard and knife. Furthermore, there's no point in giving the girls a separate space, given that each member of the group took turns tending the stove every night, and accordingly, they moved around as their shifts progressed. Unless, out of sheer generosity, the boys decided to relieve Zina and Lyuda of night duty. And how the sheet curtain, used as a divider between "men's" and "women's" areas, connects to the fire-hazardous stovepipe. There, the curtain had to be attached not to the roof of the tent, but to the sides, leaving quite a lot of space between the top edge of the curtain and the pipe.
