Noble families in all ten nations were always honored to have their daughters show the spark, especially when they are accepted as Aes Sedai. So that doesn't make sense.[/quote]
That sounds ... creatively inflexible; surely it isn't inconceivable that a family would be so attached to their daughter that it would cause them considerable distress to see her taken from them? Prestige and honor are a selling point to many, I'll grant you, but it seems inhuman that every single family producing a child with the spark would gladly see that child taken from them and would never try to resist, regardless of the consequences of that resistance. As people our actions and feelings are not unilaterally predicated on logic.
