"Things NEVER, NEVER (well hardly ever) to do!
Don't threaten-you decimate your own authority.
Don't bribe-bargaining usually makes you the loser.
Don't lose your temper-a clear demonstration of lack of control.
Don't refuse to explain-they'll go elsewhere and you're on the outside.
Don't use sarcasm or embarrassment-the fastest way to demolish a relationship.
Don't dash their dreams-your ticket into the next generation gap."
