I would go back to a time when you were mine.
or listening to something, or accidentally falling asleep like fully-clothed puppies.
I would wait for a moment you were listening to me. Really listening.
I’d say “Hi” and listen till I heard your steady voice, not the one that goes up an octave when you pretend.
You would hear me then, if you cannot hear me now.
Someone else can go back and kill Hitler.
