Round and Round on the bus

I was called to get a passenger off the bus. The driver asked me to help a chinese lady who was sat at the back of the bus. We were at the bus station and she didn't want to get off.She had a piece of paper with a map on it. I looked at it and told her where to get off the bus but she didn't seem to understand. She had got onto the right bus but heading in the wrong direction.
Her stop was after mine so I stayed with her and when we got there, I told her she needed to get off. She didn't understand and just smiled at me.
