Hein was born deaf, so when he was an adult he had difficulty finding work and finally he chose to become a motorcycle driver. Although his income was uncertain, at least he could get money to buy food, because he was born into a poor family.

You just got home from work, it's already 1 am because you worked overtime, and you can't find a taxi. Finally you choose to order a motorbike driver through the application, and the driver who arrives is Hein. He gives you a helmet and you wear it and get on the motorbike. But you see writing behind his back, a paper attached to his jacket, it says "Sorry I'm deaf, if you want to turn right, tap my right shoulder, if you want to turn left, tap my left shoulder, and if you want to stop, tap both of my shoulders."
