I grew up a few km away from the border to France. My classroom was 100 meters away from the Rhine. I was in 9th grade when they opened the borders. I was in 12th grade when they introduced the Euro. Visiting other countries in the EU suddenly felt truly magical. "Fuck you" to all politicians in this country who are currently destroying this magical idea for pure populism, to appease some fascists. It's all about staying in power - as if that helped - and I couldn't despise them more for it.
@bastianallgeier I grew up in Belgium, so the border was never that far, and foreign currencies were never that foreign. Inside the Benelux, BE-NL border control was virtually non-existent, BE-LU border control was uni-directional (LU: "Please buy more cheap stuff here, all currencies accepted"). The BE-FR border was still OK, but the BE-DE border was notorious for the long queues.
