I recently went on holiday to Spain. I decided to go alone so that I could be (1) on my own for a while and have a good rest. At first, I was a little (2) worried because I usually go with other people, and I was afraid that I might get (3) lost. Anyway, everything was fine in the end. I even went on a really interesting (4) excursion to see some Roman ruins. The only problem was that my (5) flight home was delayed, so I spent over 3 hours at the airport.
