On The Bus... #1

It was an evening bus ride back home. The bus was very crowded, and I was sitting just behind the bus driver.

Bus halts at next stop, crowd rushes up the bus. A middle-aged man, probably in his late 40s, gets on the bus, and sits where the farecard machine used to be.

A few stops later, the man rustles his belongings to get ready to alight. He reaches for the bell (within an arm's length), and presses it.

He gets all his belongings in his hands, and presses the bell one more time before standing up at the door.

Standing up, with his things in his hands, he makes one last press at the bell.

Some reasons I can possibly think of, to explain this phenomenon:

1.) The man's a retard.
2.) The man has a fetish for bus bells.
3.) The man has the typical Singaporean attitude: Press bell, free mah! Why? Not happy? Go complain to the NPP la!
4.) The man thinks the bus driver is deaf and blind, and/or he himself might not have the chance to alight at his destination stop.

What is wrong with this world?
