School is a bit like a prison for children. When you get out of prison you want to think about what you'll be doing the rest of the day, not what you had to go through on the inside. In addition, parents very rarely do what it takes to make a kid's day better while they are at school. You aren't allowed to let your kid just skip a week of school to recharge. So telling you that it was horribly stressful will result in a lot of nothing for them.<p>It's especially true for kids that have a demand avoidance. ADHD and ASD kids have a lot of problems with school for this reason. It's a high control environment and you have almost zero personal liberties. Some kids thrive in environments like that. A lot don't.
