Because she believed in the theory
of parallel universes,
Hallie was devoid of remorse.
If she made the wrong choice,
for example,
in her other state-of-being,
she was right.
If she was killed in a plane crash,
her mirror image lived
and was immortal.
The only thing missing,
the only imperfection,
was that she was never quite certain
at any time
in which world she was dwelling,
which she was she.
Over time, this ambiguity
threatened her sanity
and she rejected her belief
in parallel universes
and felt remorse once more.
