It is developmentally appropriate to have more hormaones sloshing around and to be therefore more reactive and emotional.
The fact that this translates to rudeness to parents is only because parents let them, thinking it's inevitable. I was not like this, neither were my husband or his siblings, neither were my friends during that period.
