Usually, Russians are perceived to be very cold and silent by the people around the world, but I often notice it that the same silent people are extremely loud and noisy when their family is with them. I often notice it especially in flights when they start behaving like they're sitting in the flight for the first time, running here and there,forcing others to leave the window seat for them and refusing to speak in English with staffs and others in the plane are few common scenes. I don't mean to insult anyone, but I'm just greatly confused after observing their irksome behaviour not once but several times. It's quite interesting that the Russians traveling alone are always exactly what they are perceived to be, cold and silent. Then, what is the reason that causes such a drastic change between the behaviour of Russians travelling alone and those travelling with family?
