There is nothing to say here. There are no words that can un-make a tragedy.
I can swear about people in the world who have become so twisted and warped that they no longer recognize the value of a human life. I can write a eulogy for the people who died and for the lives that have been forever changed. I can devote my life to words about the common theme of humanity. I can tell stories that illustrate how we all suffer and try to spread empathy through the world. I create works of fiction where characters highlight the best of humanity.
What I can’t do is re-write today’s ending. I wish I could.
