yeah! I didnt understand it. If she had to tell the truth, then she should have just stood on the road.
What was the point of trying to run away and then be run down by the bus?? was it not to have AVOIDED telling the truth?
But I'm also thinking that maybe she already had some repressed guilt, and when the truck ran her over, maybe she felt that god was punishing her for lying or something... and then he might condemn her to an after-life in hell... so she probably tried to set something right so that she could atleast have a chance of redemption in heaven.
In catholicism, priests are called for dying declarations, and those declarations are private. It is just to get off the chest something that is bothering you so that you can die in peace.
