There are many more sad stories like that, unfortunately... but at the same time, there are countless little stories like yours. Sometimes there's nothing we can do. I usually travel alone and so far, I have been lucky enough not to encounter any criminals.
I've enjoyed reading this article. Be safe on your travels, @maracuja!
PS: I have found your post because @chekohler featured you in his entry for the Pay It Forward Contest
I know there are a lot of stories like this, and it usually takes a lot to shock me, especially these days...but I really saw myself in those girls. I studied abroad in China last year and I was 21 when I went to Australia alone. I just wish they had met better people along the way, like I did. They should have been safe.
Thank you very much for reading and have a nice day :)
