A 10 year old kid recently ran away from an orphanage home suddenly finds his father and it changes his life .

A 10 year old kid ran away from a hell like orphanage , with no other way left around starts living with a drug peddler at a slum who claims to be his father which leads him into the vicious web of smugglers and criminals , from where no come back is possible . Will he ever be able to escape ? Does he have a better future ?

But how does it change his life forever? "Change forever" is a something of a clich?. Running away from an orphanage by itself would change his life forever, might it not? So now he meets a man who claims to be his father: how does that "change his life forever" versus the "change his life forever" of running away from the orphanage?

What is the specific course of his life -- aka: the plot -- that is a consequence of meeting the putative father?

Hey outlawdl and Nir Shelter please have a look:

Now going to rewrite it .

Also why did he run away now and not a year ago or a year from now? What is the inciting incident? Why was the inciting incident significant to the boy?

Hope this helps.

Does he run away from the orphanage to find his father?
