Ugh. I'm mad

Thought maybe if I came here and wrote it out I could get over it.
I had to take the car for an oil change today, so I could drive to the Marching Contest tomorrow, and I had a feeling I should go watch the end of the Marching Practice. Its close to my house and on the way. Thought maybe I'd take some pictures of the kids.
I got there and stopped the car, rolled down my windows, and hear the Director SCREAMING... at MY child.

SCREAMING his name and SCREAMING that he's on the wrong spot. It was about 3 sentences. He was out.of.control. I remained calm and stayed in my car. I sent a text to DS Tuba Dude that said Wow :-( I was WAY tempted to send a text to the Director saying, "I hope you never have to hear you daughter screamed at by a teacher, in front of 135 of her classmates." I DID NOT send that, it was just in my head, still is I guess
DS Tuba Dude was unprepared, did not have his Set Book. This is common in Tuba land, but HE usually has his and the others usually share his. Out of the 10 tubas, I think 3 had theirs today. They are (finally) blocking the ending and DS was in the wrong spot.
The real issue is ... Mr. Director gets stressed, stressed, stressed around these contests. Many kids were unprepared and he took it out on one kid, happened to be mine, and I happened to be there. He kinda sorta tried to apologize to the whole group, but didn't ever get there. One of those, "I told myself I wasn't going to get frustrated today but you guys....." not an apology.
Tuba Dude is fine, he wants me out of it. I will stay out of it. But I'm still mad

His best friend, Drum Major Girly, was mad too.

DS Tuba Dude has a close relationship with Mr. Director. He teaches him private lessons every week, leads the tuba sectional, etc. He has more time with Tuba Dude than most of the other kids. I think it was kind of like a parent yelling at a child, it happens. But I'm still mad
Ok. I do fell a bit better getting it out. Deep breathes until marching season is over... Saturday night.
