In a comment on a previous post, a reader pointed me to this article that compares the local government school to a "neighbor". It makes some really good points. I encourage you to read the whole thing. Here is a quote to wet your whistle.
Now, time you used to spend together in the evening is spent alone. Your children's free time is taken up working on projects your neighbor has asked them to do. Even your weekends are interrupted by games and parties your neighbor has planned for them without consulting you. To make matters worse, your neighbor has begun to ask you to chip in for the expenses he has had as a result of your children's visits.
This is one of the things I enjoy about homeschooling. When school is done, its done. And we can work school around our activities, parties, etc. instead of working those things around school/homework.
