Your remarks about brothers Hubert & Jack being able to carry out their duties despite their youth is quite valid. These days we suffer from another drawback: a rather misguided attempt to keep young people entrapped by a kind of enforced "neoteny" or retention of childhood traits past the time when such should be dropped. We also have examples here in the States of young military officers or poets achieving great things whilst still very young. Hope my ramblings make sense. WWL
Nice idea, a golden string. Even hotter when you think of golden piercings - but considering they might live in a dangerous world with enemies and brutal thieves ... wearing gold on or in body parts which might quite easily be cut or ripped off, causing severe and permanent damage to their bodies - this might not be the best idea (in a secured space, like the house of an admirer it would be OK, but not on an open beach - don't you think so?)
Generally good advice, but they are quite safe on the peaceful south coast of Kozosht. Also, Jack may look somewhat soft and foolish, but if anyone were to try and rob him they would get an unpleasant surprise.
