Hi my friend,
I'm writing you this postcard to tell you about my trip to London.
I arrived to London at 1 p.m. on Monday and the next day at 10 a.m. I was shopping. After lunch at 2 p.m. I visited the British Museum. It was a beautiful museum. On Wednesday at midday I took a London double-decker bus and at 2 p.m. I was at Buckingham Palace. And today on Thursday I have visited Big Ben at 10 a.m. and at 8 p.m. I was supposed to have London by Night Walking Tour, but due to the freezing it was canceled. It's a pity.
But tomorrow, I'm going to a football match. It will be Chelseas's match against Arsenal. And on Saturday I'm going to be at 9 a.m. at airport, because I fly home.
