Saying NaOnka has the maturity of a 7 year old is IMO a little too simplistic a way to describe her behavior. There's a little more to it than that. Yeah, that's about the right age level to ascribe to her maturity, but your mental and emotional growth can get a little stunted when you grow up and live in a place like South Central LA where a normal upbringing is not exactly the highest priority because you don't have a normal family in the first place and/or you and your family along with most of the people you encounter during a typical day are more worried about A. having enough food to put in your belly, and B. getting to school or work, through the day, then back home at night without getting any knife wounds or bullet holes in you, and having to repeat those two difficult feats 365 days a year till the day you die in a place where they really are difficult feats. 27 years in a place like that can mentally and emotionally screw you up but good, and NaOnka isn't the first Survivor that has happened to, and she won't be the last. She had her mental and emotional maturation process essentially interrupted at its current level because she comes from a place and an environment from which few people escape with unwarped minds, and JiffyProbe and the other Survivors would deal with her better if they understood that.
