I was HE'd all through my childhood. I went to college at 17, after doing all my exams from home.
I found that it gave me a huge degree of flexibility and choice over my education, and I was able to develop my interests and work at my own pace. I have a few close friends from childhood, and a large group of friends who I met at drama college.
Socially, I was quite like my dad until I got to about 15/16 - i.e. socially awkward in some situations and not into small talk and so on. I always took part in groups and activities as a child, and had great friends there, but didn't like taking part in activities, such as creative writing group, where children were being disruptive - it used to frustrate and annoy me.
As an adult, I have lots of friends and am educationally successful - 3 A-Levels, HND Acting, HNC Childcare and qualified nursery nurse, OU courses, and Mensa member. Socially, I am a professional actor, so spend most of my life talking to people and presenting myself well in public. I still hate small talk though, and I have never learnt how to bitch - I keep well out of that at work!
