No one tells each other anything and it's so frustrating

I can suspend disbelief for every single aspect of this show except for the fact that no one tells anyone else what's going on or what they've personally experienced.

When Jim got the phone call telling him Julie and Ethan shouldn't be playing outside so close to dark, he could have told Boyd what happened but chose not to.

This is just one example of something like this but it happens all the time. I know most times they tell someone else a couple episodes later but it's just so damn unrealistic to me.

EDIT: for everyone saying this is constantly mentioned on this sub, I went back 3 days and didn't see it mentioned.
