Unfortunately, it seems that in the wonderful OC, everyone grows up slowly.
Sophia has the maturity of a 4 years old at best.
Ashley is a fifteen years old trapped in a 21 years old.
And poor Fryan has the wits of a 16 years old.
I blame poor parenting.
What can you expect when your own mother is 32 forever and the other bimbo is stuck as a High-School prom queen?
