As a counter example, I managed to make friends with a Swiss person while elsewhere in Europe, and then later in my travels got to visit them in Switzerland for a few days. My time there was truly one of the most breathtaking and memorable experiences of my trip.
Maybe it's expensive, maybe Europeans are "cold" personality wise, but God damn they have got some incredible scenery.
This happens in a lot of countries. For me I noticed it particularly with young people in Germany, and pretty much anyone in Norway.
Can make it slightly frustrating when actively trying to learn the language by speaking with people 😅
