Amdon traveling with Uduravana

One day Amdon decides to visit Colombo with his old friend Uduravana. They were lucky and got into a bouble decker bus in Kandy. But both of them couldn't find seats near each other and Amdon got a seat in the lower deck while Uduravana had to climb the upper deck for his seat. 

When the bus traveled for about 40 kilo meters, the crowded bus was now empty and Amdon thought that he should sit along Uduravana and climbed on to the upper deck to find Uduravana was holding on to his seat in a very uncomfortable way. 

Amdon asked Uduravana; "Why my friend what's the problem? You look scared and uncomfortable?"

Uduravana looking at Amodon in a scary way said softly;

"You have a driver on the lower deck but there is none on the upper deck".
