Exchange Service
Some parents really take this “lying for their own good” thing a little too far. Apparently, this OP’s parents made up an entire government agency called the CAA (Child Assignment Agency) which is where kids supposedly came from. They told him that they could exchange him whenever they wanted if he ever misbehaved.
They even added that they were eyeing a “well-behaved little girl” but hadn’t made up their minds just yet. Aw, that just sounds terrible. Imagine growing up with a constant fear that your folks could exchange you for someone else if they wanted to. That doesn’t sound like fun at all.
