Grammaretto
A friend who grew up in a farm could drive from an early age. She was the youngest of 6. Her mother would ask her to drive to the shops.
"But I'm only 15 and can't drive on roads".
"Oh yes, I forgot", mother would reply.
That amused me. This case doesn't.
One of my nephews had been driving in fields and farm roads for years, booked his test a few days after his 17th birthday, told his mum the day before and passed without any lessons at all. No theory in those day but had read the Highway Code, I didn’t hear of any accidents, my own sons were pretty good too. More recent lads seem to be more accident prone, 2 grandsons have been quite seriously injured in separate crashes.
