You don’t even need to go live somewhere else; just visit.

I’m from Canada and went back to visit Germany and Belgium a few months ago. I already went to Germany and the Netherlands a few years ago and just used the trains. I had no fixed itinerary and was deciding where to go a day in advance before buying a train ticket to go there. It was obviously fine (most of the time) but because of how trains “work” here, I was anxious about buying tickets a day in advance, thinking it was “last minute”.

Then while I was in Belgium I had to plan a train ride in Canada a week later, and there was no affordable tickets left. I was sitting in Liège, and just bought a train ticket to Bruxelles that was departing in the next hour… while trying to book a train a week in advance in Canada, and failing to do so.

Every time I have to use a train in Canada, or just any kind or intercity service, even a coach, I’m painfully reminded of how bad it is here.
