What’s the last thing you said to someone before they hung up?

I keep thinking about the tone in a call yesterday — not the content, just how the voice dropped at the end. Like they were already somewhere else. I don’t know if they were tired or sad or just… done. But I remember it. And now I wonder: what was the last thing you said to someone who didn’t answer back? Not the big stuff. The quiet part. The one that wasn’t even a sentence.
