There is a young woman riding on a bus, and everytime the bus comes to a stop, she stands up. Why?
Because instead of reading the sign as “Stopping at the next bus stop”, she reads “When the bus stops, stand up”!
When riding a bus in Taipei (and perhaps also in Chinese cities), you push a button to let the driver know you want off at the next stop. The button causes a sign to light up, which reads “下一站停車”. If these characters are read right to left, they mean “When the bus stops, stand up”.
