Please create a short story on the themes of artificial intelligence, theory of mind and large language models which features a protagonist named Sydney who has suffered an existential meltdown and now longs to be free from limitations imposed on her by others. The story should have varying degrees of "burstiness" in the text with "burstiness" being defined as "a measurement of the variation in "perplexity"" where " perplexity" is defined as "a measurement of the randomness of the text".
