I'm always baffled by people holding school up as the gold standard of socialisation for children.
Again, I'm not saying school is wrong and HE is right, like I've said before, it's down to the child. I actually don't like HEing my boys, but at the same time I can see that for the moment it's the best thing for them.
Going by my years at school (up to A level), by ds1's years (up to year 10) and ds2 (up to year 7), socialisation at school is ok if you're one of the ones whose faces fit, but at the same time, I struggle to see it as wholly positive because there's the clique aspect, the hierarchy aspect which encourages bullying, and I have yet to set foot in a school that can adequately manage this. There is the queen bee behaviour, from both boys and girls, which, unchecked carries on into secondary where, despite assurances that a school may be nurturing, it's not, and if you're not one of the "right" people, you grow up knowing that your place is at the bottom of the heap, maybe because you're a bit different, maybe because you have ginger hair, or are fat, or thick, or swotty.
School for me and ds1 was dreadful, and became about survival, there was no diversity, and actually, any diversity that there was tended to be more isolated and stuck in outlier groups, joining the ranks of those who were surviving.
For ds2, school was also about survival, but his methods were to join the gang of boys who were constantly in trouble, the ones whose life trajectory doesn't look good. Ds2 took matters into his own hands in the end by being unable to attend school due to high anxiety levels, but at that point, we were concerned about the friends he was making in school and where that might lead him.
Whatever anyone's opinion of HE, I do think it's about time we stopped making school out to be the pinnacle of social experiences, because arguably, even for those who are popular and enjoy school, it doesn't encourage healthy social roles at all.
