Lost In Brazil

I just landed in Rio DE janeiro. I am competing In the amazing race. I was lost. I had never been to Brazil before. I found someone but they didn’t speak English I can't speak any other language and am from New Zealand. So I pulled out my phone to use the translation app but I had no service. So I asked the guy if he could take me to his house and he somehow understand-ed me. He had WiFi. I used the translation app and I asked him where Sao Paulo was. He said just use the train and wait until it hits the third stop. So I waited and it was the third stop so I got off. And went to the amazing race. When I finished the race I was happy that I found that guy.
