Don't freak out but I am part of a highly secretive agency and I have been sent to observe your every move because we have found DNA in your blood that does not belong to any living substance on earth.
You do not have to make up extravagant lies to cover up the fact that you like watching me 24/7! Plus, even if you are telling the truth I know you will never catch me because you are stuck in a room with no doors!
