By the way, isn't that last question too deadly?" "Stop being so verbose, I don't want to listen to your preaching, old woman." She looked at the "middle-aged woman" who was lying on the sofa and laughing so hard that she couldn't stand up. The young man said fiercely, as if this would make this hateful woman stop her ignorant behavior. Obviously, this did not work.
