I really feel for those girls with the complete lack of education. My friend homeschools her children, and they visit libraries, museums, and have gone on field trips like to farms, fire station etc. There is a local group of about 10 families so the children have plenty of opportunity for mixing, learning about friendships etc. The children learn from each other. When done properly, home schooling is a great way for children, but you need to use resources out there, and be willing to educate yourself. No way Sarah or Chris are in a position to teach their children anything - either educational or about life skills! They have learnt nothing of the culture of any country they have visited. They haven’t explored languages, just expect everything to be said in English! They are simply an embarrassment to the UK claiming to be travellers
