Parenting tip: Nip anger in the bud... take steps to control your own rage.
rage: noun. Violent, explosive anger; A fit of anger.
Heck, how many parents do you know who rage with anger against their children? Whether they act on that rage is beside the point: what would cause parents to be filled with rage against their children in the first place? Surely a word such as frustration, dissapointment or annoyance would be more fitting?
