Thanks, everybody. All of the above has been tried already. I had a long talk with my 12 yr old granddaughter about loosing trust and her 9 yr old brother was listening.

Both kids are grounded right now, no TV, no cell phone and no DS for the 9 yr old that is addicted to it. My son is seriously thinking of not giving it back at all.

I'll be seeing them today and I'll repeat my talk about loosing trust. Maybe I'll make it a little more graphic this time; put them in the place of the one being lied to.

When my kids lied to me, they got spankings, but Mother doesn't want Dad spanking. My son has told his kids, like I used to tell mine, that if they are honest, they would most likely not get in trouble, the bonus for honesty. It's the lying that gets them in trouble.

I just don't get it why kids lie. Do ya'll think it's an age thing?
