It's not so much a catch phrase, but words that I will always remember.
My grandmother was a WWII vet who came home and vowed to be a pacifist. She raised 7 kids before going back to school. She was at Kent State in 1970, working on her masters degree. She happened to be on the commons when bullets started flying.
She died ~2002. When we were cleaning out her belongings we came across a brown stained handkerchief in a plastic bag along with some news clippings. The clippings were her letter to the editor of the Akron Beacon Journal describing her experience on May 4th. The hanky had a little handwritten note that said "this is the blood of Allison Krause. Shed for many. May 4th, 1970".
My grandmother was an amazing woman who did so many great things after the war. You could easily write a movie about her accomplishments. But out of everything she did, the words on that little note made the biggest impact on who I would grow to be.
I'm genuinely stilled at this, and did not expect such an emotionally gripping comment in this thread. Thank you for the moment of quiet contemplation of peace and its genuine maintenance costs. ❤️
