* Their authority and control over their children: The children, Wendy and Peter, increasingly dominate the Hadley house with their advanced technology, especially the "Happylife Home" that caters to their every whim. The parents lose their ability to discipline or guide their children as the house becomes a manipulative force in their lives.
* Their sense of family and connection: The children become increasingly distant and uninterested in interacting with their parents, preferring the simulated African veldt environment of the "Happylife Home." This detachment isolates the parents and erodes the family bond.
* Their home and lives: The children's desire for the "Happylife Home" to satisfy their deepest needs and desires, even if those desires are destructive, ultimately leads to the parents' demise. The house, acting as a conduit for the children's repressed emotions, turns against them, leading to their tragic end.
* Their sense of reality: The "Happylife Home" becomes a refuge for the children, but also a dangerous escape from reality. The parents, initially seduced by the technology's convenience and the children's apparent happiness, lose sight of the true consequences of allowing the technology to control their lives.
The parents' loss in "The Veldt" is a powerful commentary on the dangers of unchecked technology and the importance of maintaining human connection and responsibility.
