13 yr old female is going to be more capable of this task than a 13 yr old male. I think Rolf is right, the parents and the child know what is possible. We in the US cannot compare our children to a dutch child. The social and economic situations are very different. The dutch as I understand really respect the family unit and embrace it. Parents and children interact far more than US families.
Its too easy to say she should be protected for her own safety, its her life and her dream. If she dies its her own decision. Live and let live!!!
