Who Am I?

Come, Sit, and DONT MOVE!

If you have to fidget make sure I don't notice

or else...

Just sit there and listen

Listen and make sure you memorize every single thing that comes out of my mouth

or else...

Can't stay still any longer?

You better come up with a lie convincing enough for me to let you go

And don't take more than 5 minutes!

or else...

OR ELSE WHAT?!

Or else I will destroy you!!

Every dream you ever had I will crush

Any goal you were working towards I will end

I hold your entire future in the palm of my hands

Who am I?
