Inktober Day 18: Deal
Fun worldbuilding fact, among the 4 court a childs first words are typically some kind of affirmation so that the parents can trick their children into their first "deals" or "promises" as fair folk. These promises between parent and child are typically a protecting so that the parent may take on any transgressions or mistakes the child garners, protecting them from manipulation from others and allowing their parents to handle anyone trying to deal make with their child until they are old enough to handle themselves. It also gives the children a safety net whilst they're learning to deal craft as well!
It is also used by parents like Lorg to try and find ways to manage their children. Making deals with extremely young children to lock them into quiet time, or behaving.
