"The difficulty is not guessing the riddle. It is to explain the riddle" anyways, let's start.
Really, you square me and cut corners of the square just to explain.. that food is equals to 4?! Disgusting false misleading proof.
Well, yeah, I am commonly known to be related to that food.
So kids sometimes draw me, but most of them made me ugly or became another form that looks similar to me but stretched.
I know some people say that I can't be inside that 3 dimensional blocky game or it breaks the game! Look how powerful I am!
Let me just be honest with you. You suck at counting how many sides I have. By the way, "infinite" is not a number, nor an answer. (Maybe no need to explain this, because I believe this is depends on your belief.)
Even in the kids drawing, I was commonly quarterly drawn with lines flying out of me.
A multiple of me would be helpful in showing how primary and secondary colours relate.
Also, people "draw" me to shut another people out in heretic and rebellance. But with the power of love, one can win by "drawing" a bigger me!
So, what am I?
