Have You Seen My Child?

Route 17? Xiao Gu turned back to look at the bus route map. The bus for Route 17 would not pass his apartment. I need to take Route 104 to the end and walk for another two blocks.

According to the map, the last bus for Route 104 would be at 9 pm. Xiao Gu sighed in relief when he saw that. He leaned against the bus stop and waited patiently for bus on Route 104 to arrive. The bus for Route 17 stopped by the bus stop. The driver was a middle-aged man with little care for his appearance. After the passengers got off, the bus did not leave and waited where it was.

What's the meaning of this? Xiao Gu did not plan to take this bus. He lifted his head to look at the driver and saw the driver staring at the space one to two meters in front of him like there was someone standing there.
