A.S.
I always wish there was a hybrid of homeschooling where kids went to school 2-3 hours a day, and did the rest of their work at home.
We homeschool now, but my kids were in school for a long time. I think, for some kids, it's just alot to sit in that traditional school atmosphere all day. It alternates from being over-stimulating with all the other kids, noise, lights, things on the walls, etc. - to being really dull content-wise sometimes. I didn't like it much as a kid, yet I loved college. I think part of what I liked in college was going back to my dorm, having a break, and then going back out on campus.
I'm not sure what I would do if this were my daughter. I wouldn't like the faking of illnesses, but I would strategize with her on ways to make school a better fit for her. I would also thank her for being honest with me about it.
Good luck.
