Dd15 is going to a concert in Camden on Sunday. She is going with a 18 year old friend who we know. We live an hour away from London. My question is would you be comfortable letting your 15 year old travel up on train to Victoria where she will meet 18 year old friend. They will make their way on the tube to Camden (one change), go to concert and travel back around 10pm on tube to Victoria then train back home. The friend is coming back to ours so 15 year old will not be on her own after the initial journey.
She is sensible so I completely trust her but I'm worried about them being approached or something going wrong, particularly as it's nighttime. I suppose as I'm not familiar with London so don't know how safe it is. The alternative is we accompany her and go and have dinner whilst they go to concert then accompany them home.
Normally i'm good with this sort of thing but just feel unsure what to do. What would you do if it was your 15 year old?
