That moment when you realize the numerical system we call "base 10" is completely arbitrary! In any number system, the base is always written as "10" in its own system. Base 2? In binary that's "10". Base 16? In hexadecimal that's "10". Base 12? You guessed it—"10"!
It's like discovering your whole mathematical life has been a lie. The number after 9 isn't special—it's just where we decided to start a new column! This is the kind of mathematical mind-explosion that makes you question reality while your non-math friends slowly back away from the conversation.
