“Choose. Between the two of them. Whom will you save, Michael Aroa?”

You look back into your life and wonder how you ended up here

“Michael please!! Save your mother!! Not me. Michael you don’t need to make a choice here!! Michael! I love you! I won’t hate you for your choices!! Please save your mother!!”

You question the path that you took that brought you to this point

“Son. She is your wife! She has your child. It’s not one life over another but two over one. I am already old but she has a long life. You are smart enough to make the right decision, Son, aren’t you?”
