Would you let your 15 year old child go interrailing as Kerstie Allsopp did?
I would but then again I have 4 children and can afford to lose a few.
The reaction in the Irish Times from some air hostess with a martyr complex (behind the paywall for some reason) seems to be based on little more than jealousy of people who have more than her but I can understand why some people think 15 is too young.
If she had taken up self defense classes (Krav Maga) when I offered then I'd be more comfortable. The youngest was delighted to take these classes and will stand to him.
Those Hostel films from early noughties spring to mind and keep resetting my resolve.
