I'll tell you what the end of the world will be like. It will be a final moment; both terrible & heartbreaking. Absolute chaos. People running as fast as they ever have, cars filling every road & freeway, phone lines backed up trying to process millions of calls, fingers flying over keyboards, thumbs texting like rapid fire, long lines of people trying to cram themselves into subways & airplanes. All of them trying to tell someone else, "i love you".
It's not the end of the world yet.
But don't wait until then to tell them. The worst thing isn't the end of the world. It's what you didn't finish; what you didn't say when you had the chance.
