"I give a certificate"
Cergus in the ear (the road) was dragged by pirates, Cossacks (often the latter in the family) and other crab heads. Most often it is for something decent to bury-song (well and NZ for force majeure). Therefore, it is traditionally in the left ear - so that the right hand is more convenient. The tradition of the soldier to drag something valuable (and often on the skin, the hair of the shop not to love) is widespread around the world. Even the Sikhs (not to be confused with the Sit(x)am of the ZV) remained the tradition of a silver bracelet (to sing) and chalma - like a savannah (there is still a steel quite combat bracelet in mandatory items, but not to that).
And I also have a theory, everyone in the subject (phenomenon, tradition...) sees first and foremost what he wants to see (some then connect Moscow, even units immediately).
