Hello, and again, welcome to the Aperture Science-aided Enrichment Center— *The female voice changes to a less computerized, more darkly sarcastic tone.* Oh, let's just forgo the formalities, shall we? I'm GLaDOS, but if you've been paying attention, you already know that, don't you? *GLaDOS chuckles sarcastically.* All you need to know is that you and I are going to test for a very long time — maybe until you die. After that... who knows? I might take up a hobby. Reanimating the dead, maybe.
