To me it’s a fairly obvious question, but yes I agree; thread shouldn’t be about my question.
Any child who dies, regardless of how, is a tragic event.
In my mind, no it’s not reasonable. Of course parents know their kids best, so have to make a judgement based on a number of factors, including where they’re going, what are risks etc.
I’m a parent of a 15 and 12 year old. No way would I have allowed either of them to go out alone at that age...
