14 year old travelling alone at night

[Peacelover1975]

Niece was on holiday with us. All going well until DH received a phone call to say niece had been texting her mum to say she wanted to go home - by train, travelling through central London by herself, not arriving there until 1am. She refused to say why she wanted to go home.
Her mum said it was OK, DH and I refused to let her as we feel she's too young, not at all streetwise and especially vulnerable due to mental health issues.
We ended up driving her home, not arriving until midnight and DH, 2 year old DS and I stayed with in laws.
Just interested to know AIBU?

You did a very responsible thing driving her back- I wouldn’t let a 14 year old travel alone at night

Totally think you were right no way I’d have let her go alone

Couldn't one of you taken her home while the other stayed home? I think taking her back was the right thing to do just not sure I see the logic of all of you going.

Why didn’t one of you take her home and the other stay back with the 2 year old?

Was there a reason you all went? Just wondering whether she seemed upset or anything?

TBH, as her mother or Aunty, unless there are very unhappy circumstances, I think I'd have made her wait til morning, but you did the right thing not letting her go alone.

I also wonder why you all needed to go.

Thanks all for your replies. As it had already been a long day we was all starting to feel tired so decided it was safer to share the driving. Due to nieces struggles with mental health issues it seemed better to take her home that evening having failed to convince her that the following day we would be more than happy to drive her home. I was also nervous about staying at campsite alone with DS as he has had a few sleepless nights screaming the house down recently.

I have a confident bright clued up 14 year old dd and wouldntlet her do that. You did the right thing op.
