I'm not too far ahead of you. My eldest, also a boy, is now 13. We haven't run into girl issues yet, thank goodness, but we have experienced the gentle, cooperative child turning into a teenager. I, too, think that honesty is the most important fact. We need to help protect them, because they have very little judgement! I would suggest a book that helped me understand our new roles as parents, and it's called "Yes, Your Teen IS Crazy." by Mike Bradley. There's even a website dedicated to it, although I like Mammasource and I only have limited time on the internet. You might want to explain to your son that 2 weeks is a lot for you, too, (even though he won't believe it) and that 2 weeks is the punishment because the lying doubled it. After 1 week, you might want to provide options to start building your trust back. Give him opportunities to tell the truth, role play about ways to discuss social situations and how they can be handled. In my humble opinion, the stuff that makes our kids have values and self-respect are instilled before they are 10. Now, we just have to hold on, be fair and consistent, and believe that after the testing is done, they find their own paths. My son hasn't been caught directly in a lie, but even this morning on the way to school, he informed me that he's determined that, "Rich people lie and that's how they get rich." (We're not rich, but boy wouldn't it be nice, especially if one is 13.) I was just shocked and didn't know what to say. I was brought up in a pretty religious Christian family and the Ten Commandments were stressed regularly. I haven't done that same religious upbringing with my kids for lots of reasons, but believe me, this morning I wished I had. One issue that my son is trying to figure out is the big lies and the little lies. For example, if he says he read 30 minutes on his reading log but he only read 15 and got the expected number of pages read, is that ok? We stress that the choices we make for him are based on his maturity and risk of getting in trouble or a situation that is over his head. But more and more he wants to make choices for himself. So, I also advise that you clearly give your son opportunities to make choices and then enjoy or suffer the consequences on his own. And there are still some things that parents get to decide such as dating, getting into cars, curfews, "hanging out", etc. and that is because we care. I know it's an old cliche but it still works. Psychologists have told me that the most important thing is to keep the communication going and with teens, it might take some creative work or even a bribe to make that happen. Stay in touch. I feel your pain!!
