A Quote from Portal 1
GLaDOS
There was even going to be a party for you. A big party that all your friends were invited to. I invited your best friend, the Companion Cube. Of course, he couldn't come because you murdered him. All your other friends couldn't come, either, because you don't have any other friends because of how unlikable you are. It says so right here in your personnel file: "Unlikable. Liked by no one. A bitter, unlikable loner, whose passing shall not be mourned. Shall NOT be mourned." That's exactly what it says. Very formal. Very official. It also says you were adopted, so that's funny, too.

Area and state regulations do not allow the Companion Cube to remain here, alone and companionless.
Remember, the Aperture Science Bring Your Daughter to Work Day is the perfect time to have her tested.
You are not a good person. You know that, right? Good people don't get up here.
