I need an answer to stop people in their tracks probing about home ed. I'm not being defensive but I'm beginning to tire of being asked the same thing over and over again. You know:
How can you possibly teach him?
What about socialisation? I've nearly lost a few friends by saying school socialisation is abnormal! 
What about your free time?
Or just their opinions or the look that they give you.
So any advice for a sentence, or two, that's non-confrontational or defensive sounding that will make them think I'm not bonkers and will cut the conversation dead...oh, without it being awkward?
Am I asking the impossible?
