*The voice sounds slightly monotone, with a few sudden spikes in the tone*
Miss Valdez,
This message may, or may not come as a "surprise" to you. The contents of the message, rather than the sheer existence of it.
Expressing gratitude. While in most cases, these two words would be enough, "I" am to extend the content of this notice/memorandum. The appreciativeness comes from a set of reasons, as displayed bellow:
Being recognised as something that is more than just an intricate device of metal.
Your approach towards the unit, that is I am.
Suppressing the emotions of adjournment, even when my presence was undesired.
Sharing your knowledge on expressions, unknown to my unit.
A machine has limited understanding on gratitude. The willingness of one towards the other, however, can easily be recognized. Even without having to learn several patterns. Especially in "my" case. A faulty machine, with learning patterns way too complicated to reach the desired effectiveness. This however, "I" can easily fix with time, and continous operation.
That leads "me" to the point. Continous operation. The installed batteries "I" have, no longer provided a sufficient energy output. Fixated to a charging port would further reduce my effectiveness, robbing "me" of the possibility to interract with "anyone" in person. There always was a secondary power source at "my" disposal. A miniaturized fusion reactor. An explanation of the device, and it's hazards is redundant.
"I" have inserted a fuel cell into "my" generator. Instability. The collapse of such a device at an inappropriate time, and place, could cause harm to any organisms, and lastly, to "myself".
My course is now set. Towards a sun, in a(n) uninhabited system.
*As the last part of the message starts, the tone becomes rather melodic. The intonations being in order at all times*
You appear to be the last one I have interacted with. A message of goodbye seems to be the most "humane" thing I will ever achieve. With that , I have reached a desired resemblance. So to say, I have lived a full live, in the few years of operation I was given. I can't be thankful enough to you. The Maltese lady, who expressed a completely different attitude than I would have expected. I hope you will always keep this virtue of yours.
Our existence is but a fleeting moment in the vast eternity. Its only meaning is the one we give it ourselves and I can only hope that in your final hours you will find yourself content with what you have achieved, experienced, witnessed in your time in Sirius.
