Answer:
When I was eighteen I decided I wanted to travel alone. I bought a ticket to Australia, I packed my bags and I left for the airport. I had to do a scale in Italy and then I had to take the flight there to go to Australia. I had to wait four more hours and I was sleepy so I decided to take a nap and set an alarm to wake up in time for my flight. But I didn't. I missed it and I got stranded in the airport for one whole day. It was the first thing that went wrong but not the only one. When I finally arrived to Australia, I had a lot of bad experiences. I felt lonely, I lost money and I missed home. However, I also made friends for life, I discovered amazing landscapes and I had the time of my life. So, nevertheless, it was my best experience.
