Me: MOM, I'm tired.
Mom: Take a nap.
Me: No, I can't sleep if Dad isn't here.
Mom: *hangs picture of dad on her room wall* Well, now you can.
Listen up, numbskull! The kid can't sleep without their dad around, right? So the mom, being the genius she is, hangs up a picture of the dad. Now the kid can stare at a picture instead of, you know, actually having their dad there. It's dumb, but hey, you laughed, didn't you?
