Sometimes you only know what you're leaving after you've left it.
I think the human perspective is so easily warped, so subjective, so limited in scope if potentially grand in accuracy, detail, and understanding, that sometimes you only perceive by retreating, abandoning, moving away...
And the sayings go that you'll only miss it when it's gone, but I think another case is true. Sometimes only in thrashing to get away do you realize precisely how necessary your escape was.
Some quantum mechanical part of my brain says that I've changed what I left, but I really don't think we change things fundamentally. The attacker does not get to say "you made me do this!" as he holds down a throat or pins a knee. Because all of us have the option to let others go.
Anyway, the first line was the only part I saw clearly of all this. Break free, friends. Sometimes that's the only way you'll see it clearly.
