What should I do if I want to travel during the summer vacation of my senior year of high school, but my parents don’t agree?

I believe your parents consider safety issues the most. Nowadays, reports of travel accidents appear frequently. It may be different from your eagerness to use your vacation to travel. Your parents have seen and considered more. If you have no short-distance or domestic independent travel experience before, I also recommend not to act rashly, because there are too many emergencies when traveling independently, not to mention going abroad, and then everything will not work. But if you have had many independent travel experiences before and have good autonomy, you can try to negotiate with your parents. Of course, it is best to have someone who takes care of you to accompany you when traveling. You are too young to have experienced many things now. It is recommended to travel domestically first. Whether you are accompanied by an adult or not during the trip, try to be able to judge and deal with problems by yourself and deal with them rationally. In this way, you can be independent. Get your parents' approval, and secondly, exercise your ability to deal with things, especially in emergencies.
