Dear Roger: Pride Goeth, Hopefully Before Next Fall

My eldest son got a bit of a wake up call yesterday, and I think it has left him feeling like hes been smacked in the pecker with a rolled up newspaper and rightfully so.
He is a talented, natural musician, one of those disgusting people who can pick up any instrument and after a short while, play it like they were born with it in their hands, his latest feat is to play the Imperial March every time I walk into the room, no matter what he had been playing because I told him I killed off a character in one of my stories. Yesterday he was sitting on the couch playing Shy Water, working out the mandolin part on his guitar, when I walked into the room, so key the March, then he got bored and started playing Fur Elise mashed up with Millionaire and then Caress Me Down. He just effortlessly blends and plays songs now, and when I commented that I was proud of him for learning Shy Water on his own when requests for the guitar tabs had gone ignored, he snarked at me, "Gee mom, did you really think it would be rocket science?"
Hes gotten cocky. He has a fantastic voice with a vocal range that has had his choir teacher having 10 different fits trying to keep him attending after he transferred to the online program, in fact, we waded through a myriad of paperwork and hassle to ensure she could keep him in concert choir, and hes had a couple of solos where he played guitar and he was being groomed to be part of her elite championship performance choir, but then he got lazy about showing up.
He spends hours everyday playing his guitar and when the mood strikes him, he will even take out his violin and play it, he has continued to try and work out how to write music on his own and hes come up with some really interesting tunes as he keeps experimenting with his style, but he hates having to follow others rules and agendas. I don't know where he gets that...
He went yesterday to audition for his spot in concert choir for next year,(a requirement for all Jrs.) and while the Director raved about his fantastic range and about how well his voice has developed, as has his musical ability,and she even told him that she would love to have him as a soloist in her elite performance choir,(they wear tux's) as anything from a tenor to a baritone, she was hesitant to spend any time on him because he was unreliable. She flat out told him to his face in front of everyone that while he was amazingly talented, and had the chops to go far, he wasn't going to unless he found the drive and the ambition to take him there.
I think I love that teacher now. I've been telling him that for what feels like forever, but it just went in one ear and right out the other. He blew me off and acted like he knew he was going to just have everything he wanted fall into his lap. He tells me he likes the rush of having to get everything done last minute and the pressure of looming deadlines, (hes buried in schoolwork), but I've tried to tell him that if makes him look like he is flakey and that he half-asses everything. What is really disgusting is while he lets the schoolwork pile up and then rushes though, he ends up getting A's on it! That pisses me off, nothing should be that easy for him and I hope that this teacher threatening to deny him the spot he wants as a soloist with that elite choir will be the one thing that sparks a fire under his ass and gets him working in a more reliable manner.
Hes going back to regular High School this next year and Stevie is going back to regular elementary school, though she will be advanced a grade or two ahead for her age and she will be getting some additional Gifted support through an online program at home. They have missed the socialization and all the extras like the music and art that the public schools have and I have missed my sanity. Trying to herd two kids through lessons on a daily basis while writing, keeping house, working, dealing with two other kids, including one who got in trouble yesterday for mooning an entire class, is exhausting, stressful and has lead to me constantly having to be the ,"Bad Guy" and im done with it.  We are going to try going back to the,"Normal" this next year to see if it keeps the insanity level down, and hopefully my son will decide that actually showing up and doing what he is supposed to will work better for him that sitting in the living room playing his guitar where only his long-suffering mother is around to hear.
