Not really; the age of [about] 12 has been, in many places and times, the time where one participates in a "coming of age" ritual (Bar- and Bat-mitzvah for modern-day [religious] counterparts) -- such rituals/rites are very good in the sense that there is a definite "line" for being an adult.
It probably doesn’t matter, because it’s essentially a death penalty offense, between the girls brothers, father, or, for that matter, the GUY’s father.
