It makes me so sad and worried for Mia (and Sienna) that they're not getting an education. I missed the majority of my school years due to illness and long hospital stays, and when I was well enough I had a tutor home school me. I managed to get my maths and english GCSE's but I have struggled to get ANY job because of my lack of education. I'm intelligent and once people meet me I am offered opportunities, but sadly that's not how most job applications work. Qualifications are so so important.
Also there is just so much general knowledge that you miss out on by not going to school. As an adult (I'm 26 now) I have taught myself some history, science, geography etc, but I'm often aware that I just don't know things that almost everybody else in my life does.
The fact the girls have no social life or friends is the saddest part. I can't imagine being fit and well and able to go to school, make friends, etc, but not have the opportunity because.. well, because their parents said so?? It's so unfair and there is no way that their social skills won't be affected. When I was 17 I started college and I really didn't know how to be a teenager. I HAD friends and was able to socialise even whilst sick, but it was still a difficult adjustment to have a more "normal" life.
I think Georgie and Darren have lost sight of what is important, but it is not too late to get back on track, and the sooner they do it, the easier it'll be for the girls. Plus if the kids went to school, that would make them far more relatable to their audience. It's win-win, honestly.
