So if I design the uniforms, I get free tuition, right?
All the kids from kg on would have their own laptop with wi-fi, and everything transcribed onto that (for their benefit and also so the parents would know what was going on) and their homework done that way if they prefer.
Annual spelling bee, which would be like the best spelling bee ever in the United States.
Professional sabbaticals, where professionals in technical industries could come teach for a semester on the subject of their specialty.
The school cafeteria would have 4 choices every day- gf/cf, Feingold, everything mushy, and everything crispy.

And a personal note, we'd need to have both curly fries and straight fries available, because they are not interchangable. We'd need some really rockin' cafeteria ladies, but if you pay them what they deserve...
My DH is gone a lot, too. I get them up and out and do all homework, etc. He puts them to bed every once in a while. I feel bad asking him to do much. He's tired and his is not the safest job. Being tired is too much of a liability. I used to get miffed about it, but I like eating and paying bills, so I got over it. Plus, he's willing and able to be the heavy in our house (wait 'till your father gets home!) and that is worth so much these days.
I really do think we're living parallel lives, almost to the point of freaky.
Mel, it sounds like your daughter is almost looking for the opportunity? I can't really tell by your post. I know my oldest DS (also 11) has what I call a very short fuse. And he's starting puberty and it has gotten worse. It's not sensory for him though, because he will put up with it from younger children, but not from his brother. Or, he will put up with it when he's out in public because he's learned the social norm, but won't at home because he doesn't feel pressured to conform here. Something like that. I think there is specific therapy to help de-sensitize, I can't remember what it's called. Have you tried just asking her (when she's calm) why she screams? She might not be able to tell you, but then again she might come up with an answer that will help you toward helping her.
