I want to travel without company, but I dare not tell my family. Can I make up an excuse not to tell my parents that I am going out alone?

My suggestion is that you'd better go out with friends.

I have never told my family before that I went out to play with my classmates. To tell you the truth, I did make good friends during my trip, and I still keep in touch. But I also met some ridiculous people. I think the question you asked clearly shows that you are actually naive, so it is really unsafe to go out alone. This kind of insecurity is not only a single little girl, but also a lot of travel inconvenience. A truly independent person doesn't ask this question, but arranges everything directly.

So you'd better ask a good friend to go out with you.
