Also one or both of the parents have ADHD
Things going missing. Have you checked in the fridge dear?
Chairs in the middle of the room. Probably forgot I was going to sweep the floor.
That banging in the wall. It triggered a long forgotten song and they are now humming in tune without thinking.
Kid suddenly talking in tongues? Darn their audio processing is bad again today. Just nod and carry on.
Time stands still, they black out for hours. What else is new? at least they’re still on time to pick up the kids from daycare.
Sudden freezing temperatures. Yeesh they clearly were too distracted to notice the temps changes, probably should turn up the heater.
Odd messages on the mirror. Huh one of us must have wanted a reminder.
So the Kid is weird? Meh what is normal anyway, we know a good therapist and some love and understanding can fix anything. They’ll grown into it. We did.
The creepy doll gets treated as another beloved member of the family (the Kid thinks it is alive and it’s important to encourage imagination) to the point where it’s so confused and unable to do anything bad, because everything gets met with Parenting™ and why does being hugged all the time feel so warm?
The poltergeist can’t do anything to draw enough attention. The parents are bigger disasters of chaos than they could ever possibly be. So you know what? Fine! If they can’t be a hindrance, they’ll be aggressively helpful and make sure no things are ever forgotten in this house again. Writing reminders everywhere.
The house initially tries to creak and break and cause upset, but all it gets is one of the parents suddenly hyper-fixating on undoing whatever mess they believe a previous owner caused. And then getting decorated in pretty colours and motifs, because everyone needs a bit of dopamine. Apparently even a haunted house.
A witch’s curse? Meh nothing worse than living in the current capitalist hell scape how would they know the difference. And if there at one point happens to turn up an old woman to give ominous warnings they just assume the lady is lonely and neglected and we might as well invite her in for tea. And cake. And want to meet the kids? Before she knows it, she’s been adopted as an honorary grandmother.
And that’s how this becomes the most quirky, protective and loving household in the entire town.
