The bubbly girl was a machine, and therefore only had a positive state of mind, a stupor to wander around in. Teasing and ridiculing anyone and anything for no good reason, acting tough
all the time, and blurting out a
bunch of bullshit took the place of feeling anything negative about anything or anyone, including her emotionally repressed, grown, and badass self (since it was everyone else that was an unfair
hypocritical child at play in her mind).
