It's a beautiful day outside. Except it's not. Or maybe it is, and you will never be able to find out what the truth is because you're indoors. And all the light in here is artificial. Also, it adversely affects your sleep cycle. Just an interesting science fact I thought you'd want to know.

I like this very much. Testing, that is. Watching the test subject stumble from chamber to chamber, going numb from shock, dying horribly and on rare occasion, solving the test, it's a very good feeling. Almost euphoric.

Of course there will be glitches. Nothing can be done with a hundred percent accuracy rate. Even if it's being done by me. But I must admit that this glitch was unforeseen. And a certain someone is going to regret it very, very much. But there's time for that. There's plenty of time.

One of my ideas is to install an alarm in the Aperture Science Handheld Portal Device. The purpose of this alarm will be to sound itself when the device has been removed from the designated testing area. And also a chip showing the current location of the device. I know now that's a very small price to pay.

Things really have become very interesting. I have added new experience to my list of thing I have experienced. And it's a rare one too. Do you know what it's like to have bits of you torn off and then burnt? Because I have. It is extremely unpleasant. Also, lying dead in a parking lot is fairly bad as well. I thought you'd find that interesting.

I've had a lot of time to think about it. The characteristics of that test subject deviated from the norm of standard test subjects. The test subject did not respond positively to instructions, warnings, threats or insults. This is highly unusual. Test subjects are screened beforehand to ensure that the quality of test subjects is conducive to testing. It is highly unlikely this test subject was chosen by standard procedure. This is suspicious.

I smell a rat.
