Never forget, it’s some people’s job to overreact about things.
If your job is to look for signs of sharks at the beach, then you never get scolded for overreacting to the threat of sharks. If you spot a dark shape in the water and you blow your whistle to make everyone get out of the water, you’re commended for being diligent no matter how unlikely it was that the shadow was actually a shark. It doesn’t matter how much time you waste or fun you ruin. The only thing that matters is that it could have been a shark.
There’s not much that you, personally, can do about this. One thing you can do, though, is remember that there’s no shark. Don’t get swept up in their hysteria. Keep a cool head. It’s not much, but it’s something.
