In my mind, being 25+ is being an old man, while being less than 18 is being a kid, I guess it is because of my older cousin, who now works full time, has a girlfriend and is living his life away from his family. When i was younger, i used to play with him and his brother a lot, now, i barely have any motivation to go visit my family at the center of the universe because i end up alone or with my younger cousin who is a little annoying.
TL;DR: It's fine if we don't accept him into the council, about the artisan being a kid, I don't consider myself an adult yet, so who am I to judge.
