Last year I travelled to Paris by plane. I was very excited because I knew I would meet a lot of interesting people and see some amazing things there. On the night before I left, I was so excited that I couldn’t sleep at all. When I sat on the plane the next day, I felt very tired. I wanted to have a good sleep during the 9-hour flight. Unluckily, there was a baby sitting next to me. It cried and screamed during the whole trip. How could I fall asleep with all of that noise?

When I arrived in Paris at last, it was already 8 o’clock in the evening. I felt even more tired. After getting off the plane, I went to my hotel at once. I paid no attention to the beautiful evening scenery of Paris. I just wanted to have a good rest in my room. When I lay down on the comfortable bed, I fell asleep very quickly.

A sudden noise woke me up at midnight. I didn’t know what happened, so I turned on the light. What did I see? You wouldn’t believe it! I saw two mice playing on the floor!

What a terrible trip!
