About being conned

I was once conned by a schoolgirl, aged about 17 I'd say.
We were on a coach going to London.
She spoke to the driver/conductor, in quite a loud voice, about not having enough money to continue her journey onwards on the greenline bus.
Quietly, I offered her a ten-pound note (feeling, if the truth is told, rather noble) and she put my number into her mobile.

Did I ever hear from her?
No, of course not, I hear you say. 
This was a thought I had later.

'She put another nail in the coffin of her conscience.'

She and everyone else who ends up going down that road.
Let's hope she grew out of it.
