Back in the late 70's I was staying in a house in the German part of the Ardennes, the Eiffel. It was a modern and only recently finished house.
The family I was staying with were family of my neighbours back in the UK. None of them spoke a word of English.
My neighbours who were there too, spoke English, but with an incredibly thick German accent, as they only ever spoke German at home, and he worked for a big German company in London, and spoke mostly German at work too.
My parents were also there in the house.

However, I spent a night listening to two American mens voices, taking very quietly in the hallway. I couldn't make out what they were saying, but that they were Americans that was unmistakable.
The area around there had been the site of some very serious and bitter fighting at the end of the Second World War.............

Nobody in that house that night could have been making those sounds...

I wasn't scared, just thoughtful. But I remember that night vividly.
