UK keyboards have the " and the @ symbols reversed from the US layout.
And we mix and match our units of measurement.
So
milk = liters.
Beer = pints.
Distance = miles (if driving).
Distance = km if running or cycling.
Distance = inches if penis
This is a topic in the 3 body problem series of books. The aliens have photons (?) that spy on everything the humans do so the humans have no way of planning against their attack without them knowing. The humans assign a few people to make plans with no oversight and without telling anyone else their plan.
Highly recommend the books.
