She's a young 17, not a nearly 18.
She has known the boy for less than a year.
They are both still at college.
Neither of them have great thinking skills.
He is not capable of catching a train by himself.
She's never done any paid work.
But she knows it's the right thing for her to do. 
She's so young and fragile, and desperate for someone to claim as hers.
I feel we've failed her.
