There are lots of them...like reasons to be cheerful.
Likely to be individual and personal to each individual, each person, each family.
One reason we home educate because of the parlous state of state education. Have you visited a school lately? Noisy, rude, ugly, decrepit, fully detestable, and that's only the buildings
And the fact that the denizens of two schools could not stop my eldest being bullied. Emotional abuse is emotional abuse, even if it's not in the domestic sphere.
And my youngest daughter's face when she emerged from school in the last few weeks before she left. The happy child I had known in primary school had been replaced by a miserable young person I hardly recognised.
In my opinion, the internet, books, museums, conversation and other people's knowledge could easily replace teachers' 'deposits' of information.
I'm not religious but I can see that other folks would wish to extend their deeply-held beliefs to their dearly beloved children.
Thinking back I know that, if I had followed my most submerged impulses, my children would never have marched into school. They would have educated themselves, with my enthusiastic encouragement, at home where opportunities for true education abound and out in the community where they would have become valued, integral parts of their society.
I didn't like other people's versions of anything and everything being fed to my children as if they were truth incarnate.
I wanted my daughters to be able to control their own bodies, at least enough to visit the toilet when necessary; not to be controlled by those very sad people who have a need to control others. It is a form of torture to deprive a human being of the right to perform bodily functions.
Our children are not necessarily possible recruits for the army. They do not have to be taught to drill like soldiers.
I hadn't encountered wise words of the likes of John Taylor Gatto before the children were 'sprung' from school. Some years after the deregistration, those words soothed, encouraged, incensed, and informed me. I shouted 'yes, yes!' to John Taylor Gatto. I leapt up from my seat as I realised the reality of his real experiences. His knowledge. Every student teacher, every politician, every policy maker should have a well-thumbed copy of Gatto next to his or her elbow.
I digress. Why should you home educate your children? To follow an individual and personal pattern. To give your child the very best of yourself, other people and the world. To filter your lifelong experiences to enrich the milk of their day to day knowledge. To boldly go wherever your child needs you to go, and wherever he or she needs to go.
Each child knows him or herself best. Each child has a destiny, a plan. Home education is the map which fully fits the child's journey.
And that's why we home educate.
