you grow a lot between 17 and 28. you gain a lot of real world and life experience.I guess you can’t really “measure” maturity. However, let us be real here for a second. Girls/boys back home are way more mature then those in the west, mainly because of the conditions they grew up in. Her age may be 17, but she might be a lot older mentally
laakin I think he should’ve married someone older and not his first cousin
