He's gone about 15 miles by train to meet friends. Went at 3pm, to be back for 9pm. I've just had a text saying theyre staying out and not to wait up he has a key. Last train is about 11pm
I have no idea why he thinks this ok, we're generally pretty clear about rules (there arent many but theyre clear and one of them is knowing where he is and when he will be back )and he knows not to push it.
However, he's almost 18 and maybe it's not my place to control when he gets in any more? And he did let me know, but it's a school night!
