Luckily we realized we were going the wrong way after a couple stops. We tried communicating with the people on the tram to see if they could help us out, but they didn't want to talk to us, or try to understand us, they basically didn't even acknowledge that we were trying to communicate. I clearly remember some of them just staring at us and realizing we were lost, but as soon as I'd look at them to ask for help they'd look away. Anyway, we decided to hop off the tram and try our luck heading the other way. Right decision :)
