Keep Going

When i attend my math class,our math teacher told us an interesting story.It is a conversation between father and his son.For me i think the teacher told us this story is because our topical test result is not good enough.He said our main weak point is when we face questions that we can only solved half of it,we will stop and going for other questions.That's why our marks are low.
The story is about a son bringing his father back home.On the way back home,the sky are black and it seems like going to have a heavy rain..The son still drive and drive and drive.He saw there are heavy rain in front of them so he asked his Papa
Son:Papa you are not in a hurry so may us just stay here and wait the rain go away??
Papa:No son.Just keep going.
So the son just obey his Papa and keep going.Suddenly the son start singing a song
Son:Rain, rain, go away.
               Come again another day.
                         Little Johnny wants to play.
       Rain, rain, go to Spain.
                Do not show your face again.

                                   
Papa:What the f*** are you singing.Stop that.Just remain silence and keep going.
Son:Oops,sorry dad i just want the rain to go away.(Erm...start from the son singing that Nursery rhyme,i added it myself.The teacher didn't say this part.Hahaha)
After ten minutes, the son cannot stand anymore of this heavy rain.So he asked again his Papa.
Son;Dad, the rain is too big.I think we have to take break a on the side of the road first.
Papa:No son.Just keep going.
Then, the son just keep drive, drive, drive, drive and drive.
When he was driving, he saw a lot of cars parking at the side of the road to wait for the rain to stop.
This time he asked his Papa again.
Son:Shall we.........??
Papa;No son.Just keep going.
The son had made a decision to drive slowly and not to ask anything again.
Finally, he had drive out of the raining area.Now, the Papa ask his son.
Papa;Do you know why i just call you to keep going??
Son;Yes dad.You want me to keep trying/going even we face problem.
Papa;Good job son.Now you can see those driver who stop at the side of the road are still in the heavy rain.They will still stuck there if they do not keep going.
