xxx: Tonight I was driving with a friend on a 8 trolley bus, it was empty. We looked into the rear window, and there was a 7 trolley bus, and twisting some tricks, driving a snake, and the driver smiled at us and overtook us. Then we walked around him and smiled, and then he again. After that, when the seven turned, the driver smiled to us again and waved. It raises the mood :)

Yyy: I also chased in the metro in Moscow
