Alternate Existence [Android]

I am currently 22 years of age. From childhood, I have no recollection of my parents, their identities, or whereabouts. In my early years, I resided with an elderly woman, yet that arrangement was not permanent. Eventually, she transferred my care to the foster system, and from there, I moved between various foster homes, much like a pinball ricocheting around until a particular event brought that period to a definitive halt. On the day that incident occurred, I departed and resolved never to return.
