The news of another mass shooting has me reeling. I don't want to make a speech. I don't want to rant. So I'll just quote a very wise soul. He's talking about a different situation, but it fits:
"Saruman believes it is only great power that can hold evil in check, but that is not what I have found. I found it is the small everyday deeds of ordinary folk that keep the darkness at bay. Small acts of kindness and love. Why Bilbo Baggins? Perhaps because I am afraid, and he gives me courage."
