Have you ever experienced that someone came into your mind all of a sudden and you missed them very much? If you have, what would you do? As for me, I will plan a trip for the place where I have spent time with him. The purposes of travelling are different for different people. Sometimes, having a trip with family is my best choice. Enjoying different scenery and eating tasty local food with family can be really nice. But sometimes, travelling alone is my favourite. I just want to somewhere I have been to before. When I walk by the familar streets, buildings and parks. They reminds me a lot of things happened on me many years ago at the same places. It's a specific feeling which helps me feel relaxed. Meanwhile, I spend less money than travelling with family or friends. So, what's you experience about travelling alone?
