sorry, but I am gonna have to be a square!

Yup, you are!!

I was not a square.

can I choose to be an octagon instead of a square?

I did not give choices, Sensei. You are a square!!

no choices?....what about a circle...

What part of no choices don't you understand?? You are a square and cannot become a circle, an octagon, or any other shape. SQUARE!
