I need a fix cause I'm going down

I met her when she was still just happy and shiny. Her blond hair had volume and light, her small eyes were alive and she talked loudly whenever she felt life was good and things would only get better and better. But halfway through the night (it was at a party or something), she showed me the first signs that things most probably were going to get worse. I can't remember what triggered such strange reaction, but she suddenly fisted the table and told a girl to shut it, because she didn't know anything about life. All perplexed eyes moved rapidly into their orbits as guided missiles towards agitated targets, while she and the girl digladiated in silence. At first, past the chock, the offended one stood up and tried to climb accross the table, struggled to reach the "blondie" (as she squeezed between clenched teeth), hands holding her back. For a few seconds Eleanor stood stil, unaffected, and then turned around, gave the fisty girl her back and walked away, as if no sotrm had been. Then, following this disturbingly serene response, the girl screamed at the already far away Eleanor: "You freak!". And that was about enough to turn her back into the old smily and shiny to whom I was introduced. At the time it wasn't clear to me what had happened, it seemed like a normal irritated reaction anyone could have on a bad day. But later on I would understand the real meaning of the weird episode.
