(This time Victor is in London)
A.: What do you think of a ride through London on the top of a double-decker?
V.: A good ideal The best way of seeing the streets and the people.
A.: Well, let’s go to the corner of Parliament Street, and wait for a bus there. Look out for the one that runs from Westminster to the Bank.
V.: I see a number of buses, but how shall I find the right one? Each of them is but a mass of advertisements.
A.: Let’s ask a Bobby then. Policeman, which of these buses will take us to the Bank?
Policeman: The green one, sir, on the other side, cross over.
A.: Thank you.
Policeman: You see these buses are known by the colours: some are green, some red. They also have the names of the places they go in front and behind.
