Oh yes, this sounds familiar. My daughter (recently turned 14) and I lock horns frequently. It's very tiring. There are many days I think, "I'm not sure whether it's going to be her or me, but I'm pretty certain one of us isn't going to make it." If it's any consolation, at about 14, my oldest son was a pain in the butt, too. He is now 15.5 years, and I see a light at the end of the tunnel. Thankfully, the teenaged selfishness is starting to fade, and maturity is settling in. I read your posts, and it's clear you are an involved and caring father. While my opinion is from afar, I think that - despite today's hard work - the groundwork you're laying today is going to pay off. But in the meantime, you're totally right. This only parenting thing sucks. Good luck!
