Double Decker Bus Ride

Udurawana and a friend Amaris went to Colombo. They managed to get into a double-decker bus. Amaris somehow managed to find a seat downstairs ,But unfortunately Udurawana got pushed to the top.

After a while when the rush was over, Amaris went upstairs to see his friend Udurawana. He met Udurawana in a bad condition clutching the seats in front with both hands and saying his prayers, scared to death.He asks,"Oi Udurawana! What the heck's goin' on? Why are you so scared?... I was really enjoying my ride down there?

Udurawana mumbles "Yeah, but you've got a driver."
