Travelling
- Hi, Peter. Have you already planned your summer holidays?
- Yes, I have, Nick. I'm going to London. It's great! But I remember you wanted to visit Paris.
- Well, I wanted to go to Paris at first, but my pen friend Henry from the UK invited me to spend a week with him.
- Have you decided yet what means of transport you are going to travel by, Peter?
- I wanted to travel by bus because it is the cheapest way of travelling but this trip will take a lot of time. So my parents advised me to go to London by plane. You know it is the fastest means of transport. I have already booked the ticket.
- What sights are you going to see in London, Peter?
- I hope to see Westminster Abbey and have a ride on the London Eye. But most of all I want to visit Buckingham Palace because this is the Queen's home in London.
- Would you like to visit any museums? There are a lot of them in London.
- To tell the truth I'm not fond of visiting museums. I haven't decided yet.
- When are you leaving, Peter?
- In two weeks, on the 14th of June.
- Will you bring me a souvenir from London?
- Of course, I will.
- Have a nice trip, Peter!
- Thanks, Nick.
