I'd be in jail, I swear to God. I'd be in jail if my kid or even stepkid swore at me. I have visions of the kid who ever swore at me with his teeth firmly implanted in dry wall with a few teeth missing. See why I didn't have any kids? I can't take this.
My parents corrected that kind of behavior with their own methods: my mother gave a swat on the behind; my father put a vice grip on my arm and warned me not to do it again. Did the trick. I was corrected early. "Time-outs" would have been a
haven for me. I would have done anything to be
left alone. But instead, my parents
parented and
corrected rather than ignored. I didn't swear at them later.
"Time out's" = time to work your parents better next time. Give 'em a good swat or pull on the arm to force them to TALK IT OUT -- and you actually get feedback from your kid, which is called communication, which seems to be a lost art with (especially single or otherwise divorced) parents.
Bottom line = kids swear at their parents because the parents
let them. Thank God I didn't have that luxury.
