A taxi driver was driving a taxi during night time.A girl with long,straight hair,wearing white long dress asked the taxi driver to stop.She went in the taxi and asked the taxi driver to send her to a spooky and groomy graveyard.The taxi driver felt a bit bit excited cause the girl's quite good looking.
When he was driving,he keep looking at the back mirror..as he's looked it,he cant see the girl.But when he turn to the back,the girl was sitting politely and smiling at him.Now,the taxi driver becomes more and more nervous.
As he reach a traffic light,he had to wait for the light to turn green cause at that time it was red.He got nothing to do so he look at the mirror..1 more time.The same!!He could see nothing on the reflection from the back to the mirror.He quickly look back but he could see the girl!!!At this time,he was praying so hard and his heart bit become faster and faster and faster.He started to shivering and the girl called her cause the light has turn green.
He keep on driving with the quick and unnormal heart bit.When he tell himself not to be afraid anymore,he sudenlly step on the fast break.BANG!!!!The taxi sudenli stop and knock the car in front.It was an accident and when the taxi driver looked back,he saw the girl's nose bleeding...he was so afraid~~~BEWARE!!!!

Now,i got 2 questions.
i.Is the girl gh0st or 0rdinary girl???
ii.Why is her nose bleeding that time???
