Kid gave a reasonable answer without all the math bullshit

When I was in elementary, my teacher said that “Lutetia” was how the Romans called the city of Liege. As an avid reader of Asterix comics, I knew this isn’t true and corrected her and said it was the Roman name of Paris. She insisted that it is Liege. Anyway, the next day, she came back to class and said that she looked it up and that I was indeed correct and Lutetia referred to Paris and gave me a chocolate bar.

In elementary school our teacher asked us to spell the current year with roman numerals, so I worked out “MCMXCVIII”, which I was quite proud of. Instead the teacher came back at me quite snarky and said it’s much easier to do “IIMM”, just substract 2 from 2000, duh!

It was only years later when I accidently learned that he was indeed full of shit and I was right all along.

It would’ve been easier to pretend it was 2000 and just write MM
I’m pretty sure people would have caught on to pretending it was two years in the future :)
