ok so for all of my life i thought everybody knew that a number or letter has a color? like, A is red and stuff? but apparently not? I asked my friend's sister what color a number was (can't remember what number, i think it was 1?) and she was like "??? the f.uck are you talking about" and i didn't know that this was something only certain people did

my irl friend does this too, but we don't have the same colors. like, for me, A is red, but for her, A is dark blue
