If I had an alter ego when I was young, it probably had 4 of its own knockoffs delegating each one with a thousand unnecessary thoughts.
If I had an alter ego at any point it probably escaped in the middle of the night when shadows can't be detected, and flew straight to heaven, demanded an audience with God, Jesus the Holy Spirit and all the angels.
If I was assigned an alter ego It was the first of its kind to deflect and run off becoming some attraction in a way off land just so it wouldn't be found.
