Rather than hijack another thread I thought I'd ask.
DD is almost 16 and DS is almost 24.
I allow her to go on a train to DS by herself. It's 1hr 20 mins on the train, direct from train station to train station and DS lives 2 mins walk from the train at the other end. 5 min walk at this end.
She has been known to text me on a Friday lunchtime and say "Can I go to DS's for the weekend? He says it's ok" and if I get an OK from him I come home to an empty house
. They then do whatever they do for the weekend and she comes home on the Sunday night.
Is she too young?
