Oh BTW - she is 30 years old, but acts almost like a teenager. Very little common sense and real-world knowledge.

When growing up, she apparently was completely normal as a kid. But her parents moved to Nigeria for several years, and she lived there during her high-school years. After that experienced, she changed into who she is today.

I wonder if there was some kind of traumatic event that happened there, but her family says nothing like that ever happened...
