Please do not laught at this.

I was on the bus, on my way to school earlier on and I witness this situation:

A boy practically just stood up when the bus stopped at the traffic light.
He moved towards the exit door and tapped his ez-link card, then he waited for the door to open.
However, the door didn’t open and the boy started to panic frantically.
Then he started to tap his ez-link card rapidly on the machine.
He scratches his skin head a few times. Getting paranoid, he went over to the bus driver and started to scold him!
The next thing he knows, he was so happy that the door opened and he went down.

The boy was like 8-9 years old and yet he didn’t know the mechanism of a bus? He just need more educating from his school.
