AibOP (am I being over protective) to have said no when dds friend came knocking, asking if she would like to be dropped off at the park by the girls mum and play unsupervised then collected by her mum again?
They're 10 and a half.
I'm not the over protective type. I let the dcs play out with their friends unsupervised on our road. But the park seems like a bit too far for 10 year olds even if they are being dropped off. The park is very big and there's loads of entry points and bits you can't see.
