I donโt think the German people at work know that I can now understand most of what they say, despite not really speaking any German (because I never practice, nor care to.)
That kind of thing, I learn fast. Iโm the exact opposite in languages as compared to math.
In languages, I can just play. Iโm top tier, and thereโs no reason to be modest. It just is. In math, I just canโt do anything worth a damn, and the things I can do I forget quickly.
