Yes. I've had a few experiences of travelling alone. Every time I travelled alone I would feel a bit stressed. Because when you travel alone, it usually means you don't have any friends or family members to rely on. Before the trip, I had to force myself to plan everything in detail to avoid missing any flights or trains. So, that was a lot of pressure for me. Besides, while travelling, I had to be really careful about my personal safety, especially as a girl, you definitely needed to be on guard at all times. For example, one time, I was travelling in Spain, I was walking on a street and there were two guys who walked past me, they stopped and judged me for a bit. I had this strong assumption that these two guys might have had some bad ideas about me. So, I kept walking, after a while I turned around suddenly. They were 30 meters away just following behind me. I was so scared at that moment. I told myself that I had to calm down and think about how to get away from them. So I decided to walk towards a place with more people. I found a nice spot where I had a broad view of them to see what they were doing and where they were. They could see me as well, but they were unable to do anything. It was actually funny, because we looked at each other and we both knew of each other's plans. After about 3 mins, they turned to the other side and crossed the street. You see what I mean, if you were not being alert at that moment, you probably would have gotten yourself into trouble. On the other hand, travelling alone is not always a bad thing and a good thing is that you can make new friends and talk with different people. Besides, you can enjoy yourself in whatever way you want. There will be more uncertainties. However, I still prefer traveling with friends, because we can share everything together and take care of each other. Most importantly, I’ll feel much more relaxed without worrying about those things.
