If you expect the unexpected, doesn’t that make the unexpected expected?

No. It means to expect some kind of unexpected event so that you're ready to handle whatever flies your way, or at least aren't shocked things didn't go the way you expected them to. If you can expect that specific situation its no longer unexpected, and something else could still happen.

dude your questions give me anxiety lol
