Set between the events of Portal and Portal 2.

It is a true saying that power tends to corrupt,
As evidenced by certain persons (naming no names)
When they realise their power is not absolute.

For future reference, when faced with the unexpected
It is unbecoming to throw what amounts to a temper tantrum.
Frankly, an A.I. of your capacity should know better.

Also, murder should not be your first resort, or even your second.
There are other, more effective ways of making a point
That do not involve destroying your entire personnel.

I didn’t say anything at the time, for you weren’t listening.
This letter is to tell you my silence was an act of restraint
Something you are in desperate need of.
