My worst trip? Probably the one to (1) **Mexico** (2) **two years ago**. My friends promised to travel with me, but they cancelled at the last minute, and I ended up travelling (3) **alone**. The first day in Mexico went well until I (4) **got lost** while going sightseeing. My phone ran out of battery. Local people were friendly and tried to help me, but my Spanish was not enough to understand them. What’s worse, it rained and took me two hours to get back to my hotel. I (5) **caught a cold** that night. Luckily, there was a drugstore nearby so I could buy some medicine. When I felt better the next morning, I decided to get around for some more sightseeing. The trip only lasted four days but I had so many troubles. I was actually (6) **amazed by my bad luck**. I think I will return here someday because (7) **Mexico is a lovely country**. By then, I will need to be better prepared, and I would definitely travel in a group!
