Thou shalt not say, "You're a bad boy!" Or, "You're a bad girl!" You're ATTRIBUTING badness to a child, on a level with treeness or dirtness, etc.
Rather, speak about the child's current behavior, which is a PROCESS, hence, labelled by a gerund. "You're bading!"
And thou shalt never speak of "The Blind", "The Deaf", "The Disabled", etc. Rather, "blind people", "deaf people", "disabled people", etc. A person with a physical or behavioral "problem" doesn't wish to be LABELLED by it.
WE ARE THE ROLES WE PLAY AND THE DECISIONS WE MAKE!!!
I play the ROLES of HUSBAND, FATHER, GRANDFATHER, TEACHER, CITIZEN, etsettery.
Underneath or behind all these and other ROLES is THE ACTOR with a UNION CARD (i.e. Social Security Card, listing "John Hays").
If you observe these and similar "thou-shalt-nots", you may help to PARENT AN ETHICAL CHILD.
