My father once had a funny digital realisation when he (German) phoned his German friend from Australia while not knowing that said friend was in Australia as well.
So the call went from Australia to Germany to look for the German phone and roaming back down to Australia to make the connection. I wonder if the actual signal traveled to Germany and back to Australia or if it is routed locally after establishing where every participant is.
Why the surprise? My first thought on seeing this was there must be a lot of Australia or New Zealand answers due to the relative geographic isolation of Australia and New Zealand in relation to the rest of the first world.
Denmark to US. I did walkman and cassette deck repairs before Covid. It was possible to earn a pretty penny by buying broken decks on eBay, fixing them, and then reselling them.
South or North (asking under the impression they still have occasional English teachers in the North)?
My answer would actually relate to North Korea. Dumb younger me thought "if they have no technology, I bet someone there would appreciate being a penpal". In hindsight I fear the results.
I used to sign up for a penpal thing where we would exchange letters written with a typewriter. One of the guys I wrote to was in Switzerland, we exchanged a couple letters but then he stopped responding.
