1: riley`s grade!
riley is 11, but that means she is grade 5 or grade 6, but rarely people enter grade 5 when they`re 11, and in the movie, she starts school on her "first day of school", so that means shes in grade 6.
2: something i don`t get.
in the movie, when joy and sadness returns, theres a button that says "puberty", but if Rileys 12/11, then she should of had that button two years ago!!!
