I'll never ever forget being 13 in sole care of my 10 year old sister to get us from London Stansted to Sweden where we were meeting my biological grandmother for the first time.
Had to get a train from the airport in Sweden and change trains to get to the station she would be waiting for us. First train no problem. Second train very busy and we each had a large suitcase. Pulled up to our changeover station and I was stood next to the doors with the suitcases; my sister stuck behind about 6 people stood up who She thought were waiting to get off once the doors opened. I get off with the cases, turn around expecting to see her getting off, no sign. Run halfway back down the carriage on the station platform to see her stood there still thinking the passengers are just taking their time
I bang on the window and just as she and half the passengers jump out if their skin, the beeping sounds and the train doors slide closed and the train starts moving off! When I tell you I SCREAMED... so loud the driver heard it, stuck his head out if the window and shouted at me in Swedish. I just screamed "my sisters still on the f** train! Please let her off!" Driver opened the doors, I ran back to where she was and screamed "f*** MOVE!!!" At my sister.
literally Everyone in the train station and on the train literally watched as she pushed her way through, basically fell off the train and omg did I not let go of her hand for the rest of the journey
I'm 35 now and my sister always tells the story to her kids as the only time in her life she's been grateful for my big gob!
this was before phones were common, although I think I actually had a blackberry lol but my sister certainly didn't and she wasn't very streetwise at the time and very shy. She would never have had the sense to get off at the next station and either get on the next train back to where I was or wait there for me. And she'd never have thought to ask someone for help
22 years later and I can still feel that dread sliding down into my stomach as the doors closed
