AIBU to be angry my sister left my 16-year-old alone?

Evening all,
My DD is 16, she’s in Y11. A little while ago I mentioned to my sister a couple of the areas of work my DD is interested in potentially pursuing. My sister told me that her friend’s son and DIL who are mid-late 20s happened to be an immigration solicitor and a researcher at a think tank focusing on migration and refugees. This is something my DD is very much interested in so my sister agreed to set up a coffee with them and DD so DD could ask some questions.

This coffee took place today, it’s the school holidays so I was at work and the deal was, my sister would meet DD in London at the train station and take her to meet this young couple. We don’t live too far from London but DD has never been into London alone before, not even with friends (we are closer to Brighton so they tend to go there instead).

DD has just told me that my sister did meet her at the station and accompany her to the cafe but she didn’t stay, leaving my 16 year old DD alone with this couple effectively.
DD said they were lovely and they answered all her questions and she found it very useful but she felt a bit uncomfortable. Then when they were finished she realised she didn’t know how to get back to the station for her train home. She said she asked them just for directions and they offered to accompany her back to the station and waited with her until she was on the train.

Now I’m beyond angry, my sister never implied she would be leaving DD with them and if I had known that was her plan I’d have suggested DD not go as London is a massive city and these are strangers!

I want to have a harsh word with my sister and tell her that was totally inappropriate not just for DD, but probably for these young adults who were left with a teenager they don’t know!

AIBU to be furious?

I was commuting to London for work at 16. I had my first job in the Tottenham Court Road. No idea how to get there, no smartphones back in the 70s. Train then tube. I had to use my noodle to learn.

Red bus rover? Those were the days!

Haha, not quite, this was the 90's 🙂

Your daughter needs to learn some life skills. Start with Google maps. YABVU.

I was travelling around London with an A-Z by myself from the age of 14. I think this situation is absolutely fine for your daughter, and good for building confidence, resilience and remembering to plan ahead in future.

Also concerning that the phrase or statement 'Im not comfortable', or 'Im uncomfortable' has garnered the significance it has.

True. Leaving one's comfort zone is part of growing and developing - at any age, I'm still doing it and I'm 70+.

My sixteen year old went (with a couple of mates, granted) on a week long holiday to the other end of the country after GCSEs. She was still sixteen when she navigated buses to a city she had never been to for a taster day at a uni. She was fine. I had life 360 if needed but didn’t need it.

You have an almost adult.

let go.

I think its not fair to leave her do the journey on her own without letting her know that thats whats going to happen if the teenager has never been to London before. Its not ok to just dissappear. I think your sister should have been clearer about the plan.

Equally, the OP and her daughter should have been clearer on their assumptions. Seems that both sides assumed that their plan was the understood plan.

Claudiasfringebenefits · 10/04/2026 08:43

No I think DD very overdue figuring this type of thing out.

If your sister had let her know she’d need to get some public transport I think a child several years younger should have managed it. At 16 she should be able to “spontaneously” manage this. You’re talking like asking someone for directions is something distressing, surely that’s normal to ask occasionally, even with google maps.

Brighton IS a city! My dgd who also lives "fairly close to Brighton" Very rural, also 16, travels to London on the train to meet up with people. (She is also nd) My oldest DD left home at 16, she wanted to work with horses and had to live on site. She now whips round the planet alone!

Brighton may be a city but certainly feels as a town to me.

No one is in the wrong here or being unfair. The daughter made an assumption that the aunt would be there. The aunt made an assumption that it was a given that she wouldnt be there.

Neither communicated the 'plan' and quite frankly I wouldnt have thought there would need to be an overt plan, Im introducing you to some people, thats it. It wouldnt cross my mind that there would need to be some sort of 'arrangement' to get back to the station.

GETTINGLIKEMYMOTHER · 10/04/2026 08:41

TBH I’d have been appalled to find that my dds were so helpless and clueless at 16 - and this was long before Google maps.

At that age a friend and I spent 6 days in London on our own, staying at a YWCA while attending a German course. Home was 100 miles away. My DM told me clearly how to navigate the Tube - easy! - and that was about it, apart of course from Don’t Talk To Strange Men!

liamharha · 10/04/2026 08:40

I think she's the right age to probably to start having to learn to navigate new areas and find her way on her own. ,which she did she asked the couple to help and she arrived he safely .
Unless their is SEN involved you need to back off these next 2 years are her navigation from young adult to adult ,believee in uni she will likely be falling out of nightclubs and random parties at all hours ,she has to learn to be able to navigate these situations safely and ha w some street smarts .

I was travelling on a train to London to work every day at that age. You are babying her

Gosh I was working at 16 on evenings and weekends after college, travelling to independent kiosks all over south London. No Google maps in them days either.

@Students2
Think Covid as an excuse for
inept teens/adults really needs put to bed, it’s been 6 years now.
I see on here plenty who do nothing to build their child’s resilience and see to think it’s a badge of pride that their little Matilda (who is in fact 22) needs mummy to support her.

How did you get that these sentences were some sort of excuse? “We have taken the children to London - but it’s not somewhere they have asked to go as teens. Maybe Covid played a role in that as they were not going out much during that period obviously.”
Covid happened when my kids were young teens … they didn’t ask to go to London after Covid so why is that an excuse? Sending kids to London age 15, without kids asking to go, is not a parenting must do.

You sound like many people on this thread who are getting some sort of superiority kick out of criticising other people’s life choices.

Yab massively U. The fact your DD panicked and had no clue what to do, suggests she’s been massively babied. This would be normal for a 16yo.

She didn't panic, she coped. The only person not coping here is the OP but hopefully she's rethinking her initial reaction.

My ds moved out and did an apprenticeship aged 16. My 14yo ds has SEN, and got a bus to work experience across town independently after I showed him where to go on day 1. They need to learn to find their way to a train station independently.

HoppingPavlova · 10/04/2026 07:24

I can’t imagine what the problem is? She is 16yo and it was out in public near public transport. Your sister didn’t drive her out to a remote location and leave her alone with a few strangers. You are being very odd. Does your DD not have a casual job outside of school (fast food or whatnot) where she interacts with strangers in public and gets transport?
