OH MY GOD YOU THINK ABOUT THAT TOO!?!
I thought I was only the one! I've tried to explain it to my friends but they just think I'm crazy. Like..what is blue? What if my blue is your green!?! Uhg. I'm glad someone else thinks about it too!
I try explaining it to my friends and they don't understand.
I'll say, what if the ocean to you looks what green is to me; but we call it blue? They say, "but it's the same color! we all see the same color!" - they just don't understand!
I still don't fully understand but it could be true - and we never know!
