The Wrong Train

I am often traveling between Turku and Helsinki by train because of my work. One morning I walked to the train as usual, sat at the seat whose number was marked in my ticket, and waited for the train to leave. I wondered lazily why the train was more full than usually, and sank into my thoughts. Soon there was an announcement: “Welcome to the train heading to Tampere…” I did not check out the platform before stepping in to the train, because the train to Helsinki always leaves from that track. That day the platforms had been changed, but luckily I still had time to catch the right train.
