Well done. Here come the test results: You are a horrible person.

 

GLaDOS wakes up suddenly, bolting up right in bed. Arms out to the side she manages to accidently knock the phone of the hook. Oh hey Mayfield. Have a rather distressed woman who doesn't realize where she is at the moment yet.]

Alright, I'm back. How long was I out for this....time....

.....This isn't' the ....Enrichment Centre....

.....Wonderful.

[Well at least her sarcasm is working. And she hangs up the phone after seeing it. She needs a moment to compose herself. And by compose herself, I mean throw a pillow at the wall and scream in rage.]
 

Phone
[Later that day:  Have an actual phone call Mayfield, she's muttering to herself as she picks up the phone..]

....Well I suppose this beats being a potato...somewhat. 

....

Hello Mayfield, would anyone be able to tell me if I was gone for long. I seriously doubt it`s been nine...[999-]. Well however long that was. Hundreds of years maybe.
