My 15 year flew in from the UK last week for his school summer holidays, it was a 12 hour flight.
He arrived in winter and shivered for 3 days, although the positive side of this was he was in bed by 7pm watching his TV.
I then stuck him on a train to Cape Town for 28 hours.
On the second day after dragging him around Cape Town on the red bus, he got in his pjs and didn't leave the room till day 4.
I thought I'd entered the room of a Rock Star on my return to the hotel, No, just a teenager
