Why do people say, "I'll never take it off" then do it anyway?

A friend of mine has a daughter who gave her a black leather bracelet years ago. My friend said, “it’s from her; I’ll never take it off.” Next time I saw her it was gone. Then my daughter said,“daddy gave this necklace to me. I’ll never take it off” and I’ve not seen it since. He’s still very much alive; I’m not being insensitive.” Am I the only person on here who would never utter those words? Happy New Year to everyone !
