Believe me, they're the worst ;)
My son recently got on the wrong train to get home from school, it was one that was "fast" that is it doesn't stop in the place where we live, his train sailed straight through our station and the next several stations, before it finally stopped somewhere and he got off.
At this point he (rightly) whipped out his phone and called me for help/advice. I checked the train timetables, figured out that although I could have gone and picked him up in the car, it would actually be quicker - and perhaps a learning experience - for him to get the train back.
So, I told him "go to platform X and get the train at HH:MM and it will bring you home".
He went to platform X, but unwisely got on the first train which arrived, which unfortunately was a delayed - fast(!) - service. So, he ended up going in the other direction on a fast train - and (again) not stopping - straight through our station, until his train eventually reached somewhere it did stop at.
At this point he phoned me in tears. I got in the car and drove there to pick him up.
We filed that under "learning experience". We seem to be having plenty of them...
