Dear Betty,

I hope you’re well. I’m on holiday in London with my friend Jenny. We arrived by plane on Monday and took a taxi to our hotel. I went for a walk in Hyde Park but Jenny didn’t come with me because she was tired.

Then on Tuesday we saw the clock, Big Ben, and Buckingham Palace. Queen Elizabeth lives in the Palace, but we didn’t see her! I bought some presents but Jenny didn’t buy anything!

The next day we visited the British Museum and had dinner in a Chinese restaurant!

On Thursday morning we relaxed. Then we went to Tower Bridge on the River Thames and looked at the city. It’s very big!

Finally today I did some shopping and Jenny listened to a concert in the park. I came back to the hotel and read the newspaper. Then I wrote some postcards and sent some emails. I took lots of photos and I’m sending them with this email to you!

Tomorrow we’re going to fly home. It was a short holiday, but it was great! Say hello to your mum and dad.

Love,

Gran
