We get it. It's the '80s; parents asked fewer questions then; the kids' parents aren't really involved in any adventures, yadda yadda yadda. But what about one Karen Wheeler (Cara Buono), a.k.a Mike and Nancy's mom ? The woman has been given a full character (unlike Mr. Wheeler, who could just be described as "Sleepy Old Guy") and a whole storyline, and still, she has no idea that something weird is going on in Hawkins until it's splashed across every newspaper at the end of Stranger Things season 3. Well, the actress who plays Karen has a few ideas about why Mrs. Wheeler might be a bit... distracted.
