To meet guests, receive letters or purchases from online stores, each person needs an address. And this is not always the city, street, house and apartment we are accustomed to. In some countries there are no house numbers, in some - apartment numbers. Somewhere the address will be an unpronounceable string of letters and numbers, in others - the cute "three steps from the big tree". What kind of addresses do not exist in the world! For primary school age.
