I'm going to throw away my kid's school homework, projects and other items.
Won't that cause trouble for your children?
Maybe, but it's causing a clutter.
Don't do it. Your child could face consequences if you do that.
I don't care I can't stand the mess all this stuff is making.
That's your kid's stuff not yours, it's not right for you to mess with it. Throwing away items that are important for your child's education would be really irresponsible. Use this as an opportunity to teach your child to keep their things organized.
