I know some (horrible, IMHO) parents who don't discipline their children at all. I mean
at all.* The woman has daddy issues and "doesn't want her child to ever feel like he is restricted."

But the point is, this child has a very thorough concept of possession, despite the fact that in his experience his parents have none. Everything is his in his world, and he acts like it.
*As an example, their toddler kept turning on the TV, and rather than tell him not to, they got rid of the TV and watch their shows on the computer instead because it's too high for him to reach.
