So I did it, wrote my own open letter to friends and family: http://fromschooltohomeschool.blogspot.com/
Dear Friends and Family,
We made a life decision recently that is viewed as different. We chose to pull our kids out of public school and homeschool them.
This decision is by no means a reflection on you or your choices in how your children are educated. We saw flaws and issues with OUR children's education and experiences and chose to take things into our own hands.
I never planned to homeschool. I thought it was odd, and after all-what is wrong with public school?! Nothing is wrong with how you choose (or chose) to educate your children. Whether you homeschool, use public school, private school, or a charter school. Your choice is right for you.
My honest opinion of all of my friends and family is that each and every one of you always tries to do what you feel is best for your children. In regards to everything, not just their education. At this point, we feel homeschooling is what is best for our children. Homeschooling is not for every child, and not for every family. We went into this with open eyes and know that it may not even be for us. But we felt it was right and felt we needed to take this path in our lives.
We respect everyone's decision to teach their children the way they choose, and hope you will do the same with our decision.
And for the record: just because we have chosen to homeschool, it does not mean our children are now hermits. Please encourage your children, their friends, to still call and visit. :)
