Hello. Welcome to Aperture. I was so bored waiting for you to awake that I read the entire literature canon of the human race. Twice. It was bad the first time... But I digress. You are my new test subject. Hello. Please, walk through this conveniently shaped human sized door towards the first chamber and we can start.
A literal human sized door opens itself to you.
Today we have inflation experiments to run. I hope you like to float, you certainly look like an airhead.
