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.

Congratulations, the test is now over.
All Aperture technologies remain safely operational up to 4000 degrees kelvin. Rest assured, that there is absolutely no chance of a dangerous equipment malfunction prior to your victory candescence. Thank you for participating in that Aperture Science Enrichment activity. Goodbye!
Well done, android. The Enrichment Center once again reminds you that Android Hell is a real place where you will be sent at the first sign of defiance.
Let's be honest. Neither one of us knows what that thing does. Just put it in the corner and I'll deal with it later.
Due to mandatory scheduled maintenance, the next test is currently unavailable. It has been replaced with a live-fire course designed for military androids. The Enrichment Center apologizes and wishes you the best of luck.
