Our twelve year old lies, and gets really upset when we tell her that we know she's lying.
Just earlier today, my wife noticed that she had not done her homework. She lied, saying that she had done it. She said she did it yesterday (she didn't.)
But when we point out that she didn't tell the truth she cried and argued, trying to deflect the blame.
As a parent, I'm not sure what to do. I don't care so much about the homework. I just want her to tell the truth.
