Our youngest who is a frehman in high school, just returned after three years of being homeschooled. He needed some re-adjustment; basically he had to learn to sit still for classes again. He's doing well, though, and all of his teachers like him. What he doesn't have, which amuses them, is the servile attitude of the other kids. He's used to doing his own learning, and dealing with adults without the master/slave mentality.
Maybe that's what Pitiricus felt is lacking in HS'ers... ;-)
