Hello! I was very busy last week, so I didn’t have a minute to write until today. Don’t be unhappy-I’m here now! I want to tell you about my trip to Buffalo, USA. I can’t believe I was there-and for a whole week. Buffalo is amazing! The people were very nice and, of course they speak English like we do here in London. Here is what I did on my holiday.

Mum, Dad my cousin Siobhan and I arrived on Friday night at eleven o’clock-I was very tired, but very excited. We got a taxi to the Holiday hotel. It’s in the center of the city, so it was easy to find. There was a lot of traffic, though. Buffalo isn’t the capital city of the USA, but it is a huge city. Our hotel was nice and very close to the sights we wanted to visit. It was expensive- Dad wasn’t very happy about that!

The next day, on Saturday, we went on a tour of the Niagara River. It was a forty-five minute tour and it was fantastic. Siobhan doesn’t like ferries, so she didn’t have a fun at all! She likes shopping, though, so after the tour we went to a gigantic shopping center. I got a very nice T-shirt- it’s got a picture of Buffalo on it. I also got some postcards for my best friend, Safi. We went to explore the city and saw lots of really tall buildings. There were tourists everywhere but it was a great day

I’m feeling tired now- more tomorrow!
