They don’t have the usual fear and shyness of early childhood. And tended to be full of false cheer.
I can see where your ponder is coming from.
They sort of have to be full of false cheer. It’s like the puppy in the window. No one is going to take a gloomy puppy. They have to pretend not to have any maladaptive behavior. No one wants to adopt a problem kid.
They have to fake it if they want out of the hell holes that group homes and foster homes can be. But adopted kids already know they’ve been thrown away once. Those poor kids.
(Please, I’m not saying all foster homes and group homes are holes… But the bad get the media attention.)
Yah but they burn out later. Its the same thing that effects us. This… “dna verses environment” stuff.
