It’s obvious isn’t it DOA? At that age she is probably quite small (compared to say a teenager) …. just the right height to fit inside a chimney.
She probably works for a local plumbing company where she is used as child labour to go up chimney flues and sweep them clean. I expect that they pay her a pittance to do this before going on to school – the plumber’s equivalent of a paper round.
I don’t know, the depths some employers will sink to …. Hmmmmm.
