Band camp starts at 9am tomorrow and my DS is a freshman going into the marching band this year. At his school, most of the freshmen start in a lower level band and don't go into marching band until sophomore year, so this is a big honor. However, yesterday while I was at a baby shower for my niece, one of DS's fellow Boy Scouts called to tell him that they decided to do a 50 mile bike trek tomorrow!
Before I got home, DS had already emailed the band director to ask if it would be possible for him to MISS HIS FIRST DAY OF BAND CAMP

.
I've told him and told him that 1) if I were the band director I'd seriously question his commitment and 2) if it were me, I'd assume that I would have plenty of other opportunities to do a bike trek but only one chance to make a good first impression. He refuses to listen and is determined to go biking.
He did get a response from the band director and she told him that they were going to go over the fundamentals of marching tomorrow, along with handing out lyres, costumes, etc., and working on some of the cadences. She said that it's going to be difficult for him to catch up if he misses tomorrow. She also said that she'll work with him, but she won't hold the rest of the band back while waiting for him to catch up. Which I tried to tell my DS meant that she didn't want to tell him no outright, but that it would be a really, really bad move on his part to miss band camp tomorrow.
He's 14 and thinks he knows everything, so unfortunately, DH says the only thing we can do is let him go and if he ends up falling flat on his face at band camp on Tuesday, perhaps he'll finally accept that sometimes we are smarter than he is. I just wish DS wasn't quite so independent and stubborn!
