There’s only one rule that I know of, babies—”God damn it, you’ve got to be kind.”
~ Kurt Vonnegut. God Bless You, Mr. Rosewater
Vonnegut is king.
You could write a whole post on legendary quotes by Vonnegut. Someone did, in fact.
You could fill a book with timeless quotes by Vonnegut. He did, in fact. 26 books.
Back to the quote: people have asked me, “Would you really want a world where everyone is kind to everyone all the time?”
