Hooray, I'm in London! The Barkers are very pleasant people. Yesterday we drove to the city centre. I saw the River Thames, the Houses of Parliament with Big Ben and Trafalgar Square. Mr Barker says that we are going to make a tour of the Houses of Parliament and listen to the debates in the House of Lords or the House of Commons. I'd like to do that very much! Big Ben, the famous clock, doesn't look very big, but I know that its minute hand is as big as a double-decker bus. From the Houses of Parliament we walked up Whitehall (it's not a hall but a beautiful street). We turned to Downing Street to look at the house where the British Prime Minister lives at 10. In Trafalgar Square I saw the monument to Admiral Nelson, the National Gallery (it's a big world-famous picture gallery), a church (St. Martin-in-the-Fields). Next to the church there was a street market where I bought some souvenirs for my family. After that we had dinner at a nice restaurant. The restaurant looked like an old ship. We had fish and chips and some pudding. It was fun. On Sunday John and I are going to visit the British Museum. I know I'm going to enjoy it.
