The Radius of My Brain,

welcome back, please take your seats,
i have a question for you,
but i won't ask it just yet,
i'll wait and see if you can guess,
the radius of my brain, my house,
the formula for breath,
the distance between here and this imaginary star,
a canary in space,
i'm watching you,
yes you, there in the back,
why aren't you listening,
why aren't you in awe of me,
why aren't you taking notes,
why aren't you wearing red today,
a bright day, a good day, a fantastic day,
for hearing my words,
and figuring out my motives,
you there, closing your eyes,
am i frustrating you yet,
have i made you want to drop this useless class,
yet,
have i made you wish you were someone else,
yet,
and i breathe, and i put on this tie,
it's too short and my kids laugh at me,
why don't you care,
this is why i'm here,
