To preface, the "Thousand Yard Stare" is the look people get when they disassociate. I have worn the stare many times, and it's generally after I go through such a turbulent and depressed state that my brain cannot take any more, so it just shuts off.
Anyways, I got the apology from girl in question, but I really wish I didn't ask for it. So cold. I could have sworn there was a layer of blue behind her black eyes. The girl had been crashing at my place every night for different reasons; one night, "some kids drugged her at a party", the next "her friends ditched her and she had to walk home alone". All #######4 ways to exploit my kindness, but in any event I reached my breaking point and woke her up and asked her "What the hell do you want with me?" She tried to avoid, but I persisted vigorously. Once she knew she wasn't going to get away, it was like a switch flipped in her brain. She lit up a smoke, and started muttering in a dull, blank voice about our relationship. This was when I first knew something wasn't right. I asked her why she liked me; she framed everything around herself. Couldn't list any of my attributes, just her own. "I am this, I like this, I see you like this, You try to control me, etc".
It was devastating. To hear her speak honestly and plainly for the first time. I never want this to happen again.
And yes - two stares. The first is when they're bored, and need validation. Keep in mind they are always bored. This first stare is generally focused on a mirror. Second is the death stare. And if you care about person in question, it is truly fearsome.
