Daddy, how much do you make an hour?

With a timid voice and idolising eyes, the little boy greeted his father as he returned from work,
" Daddy, how much do you make an hour?"

Greatly surprised, the father gave a look and said:
"look, son, not even your mother knows that. Don't bother me now, I'm tired."

"But Daddy, just tell me please!? How much do you make an hour?" the boy insisted. The father
finally giving up replied,

"Twenty ringgit per hour."

"Okay, Daddy, could you loan me ten ringgit?" the boy asked.

Showing restlessness and positively disturbed, the father yelled, "So that was the reason you asked
how much I earn, right?? Go to sleep and don't bother me anymore!"
Then, the father pondered over what he had said and was feeling guilty. Maybe he thought, his son
wanted to buy something. Finally, he went to his son's room.

"Are you asleep son?" asked the father. "No, Daddy. Why?" replied the boy partially asleep.
"Here's the money you asked for earlier," the father said.

"Thanks, Daddy!" rejoiced the son, while putting his hand under his pillow and removing some
money. "Now I have enough! Now I have twenty ringgit!" the boy said to his father, who was gazing at his son, confused at what his son just said.

"Daddy could you sell me one hour of your time?"
