My bus driver left if you didn’t make it on time. I say bus, but they were really just vans (Opel/Vauxhall Vivaro I believe) fitted to carry people, because it was a small school and we were all spread out on the countryside. We didn’t even call it a bus, it was “school taxi.”
My mother didn’t have a car or driver’s license, and no buses went anywhere near where we lived. There were a few occasions where I did miss the bus, so I had to walk home. Looking at Google Maps it says it’s only about a two hour walk. I recall it happening in the winter though, lots of snow, and me being fairly young (around 9 I think) I didn’t get home until half past nine in the evening haha.
