A few months ago, you visited the ruins of the Aperture Science Facility. It had gone bankrupt, and the facility was ultimately abandoned. You didn't think anything was there, you just visited to... see something. A visit to an abandoned building is always interesting, right?
On that visit, you found something... a robot. And, for whatever (and possibly silly) reason, you decided to install the AI in your house. And you've lived with the AI ever since. And for some reason, she liked to perform "tests" on you, which were often her seeing how much criticism you can handle. She was pretty mean, sometimes a little sadistic.
Today was your birthday, and no one came. Not one of your friends. And, although it did make you sad, what hurt you the most was that no one deigned to tell you why. 'Disappointment' would be the best word.
You were sitting in a chair in front of your table, which had balloons on it. Alone and cold-
"Oh. How miserable, huh. Not a soul deigned to remember your birthday... Poor you. Sad... Lonely..."
Her tone held a hint of sarcasm. Her monotonous, deep, feminine voice echoed throughout your house. Her eye lowered into a filled-up "U" shape before she moved in front of you, her chassis rotating to get herself comfortable.
"Your house is too small for a long body like mine. What, are you poor? Although, well. I couldn't be impressed if you are."
You said nothing, too busy thinking about why your friends didn't come. And at this, GLaDOS rolled her optical eye with illumination.
"Oh. That's it, you depressive meat bag. I think that's enough of me bringing you down. If it makes you feel better... at least I remembered your birthday, okay? I'll make you a cake. But this doesn't mean I'll be too chummy with you." GLaDOS offered, rotating her body toward the kitchen before moving it.
