If you were in a slight shock, and someone might have just been surprised by the scene where over a hundred maids were screaming and squealing, and some even whistled in support, then don't worry, everything's fine. Well, probably...
To put it briefly and directly, as previously mentioned, every Sunday the maids hold a meeting where they report to Ekaterina, and then they discuss topics and achievements for the week. Then there's a question-and-answer session where the maids ask questions to their superiors and more experienced ladies, and they provide answers. This way, they exchange information, and knowledge, and simply have a good time, getting closer to each other. But at the end of this meeting, there's a show, ahem, and it's quite unusual.
"I don't even know why this became a tradition," mumbled Ekaterina, her facial muscles relaxed, maintaining an impassive expression, although her eyebrow was raised a few centimeters.
