My stepson is going to be 13 this year, and lately past couple of months he has been really disrespectful and lies a lot. He will lie over simple questions, like if he brushed his teeth.... he will lie and say he did. It got to where I knew he was lying, he didn't even go into the bathroom. I have called him out on his lying, along with his father... my stepson backs his lies and continues to lie and claim he did.
