My new friend lives in Rome. I have never been there. What a good idea to visit him. So it is settled. I'm going to Rome next week.
But how can I get there? The trains are too slow. I'll fly.
The tickets are expensive, but as I am going to visit my new friend I think that I can afford it.
My mother says that I'll have to book the ticket.
By the way my mother will lend me the money for the tickets
and my brother Sam will give me a lift to the airport.
Oh, I have nearly forgotten I'm taking my girlfriend to the opera tonight.
Certainly, I'll tell her that I'm going to Rome.
Oh! And what if she asks me to take her there? What shall/will/should I do?
