I was the "gifted child". I was reading political press at 3, then was very bored at school for several years. I held full on conversations from the age of 2 and by 8 spoke fluently in four languages and wrote & directed plays at school. I had top grades and never had to work as hard as others. I won national spelling competitions.
The teachers suggested to my DM many times that I should 'jump' a year or two up in school, but DM decided I was not emotionally there and I think she was right. I was dead bored a lot of the time, however.
I then ended up scoring top for a top private international school (we lived abroad) and several high schools. Chose a slightly worse school to frustrate my father, it looked fun to me. Breezed through it with zero effort, got top grades and exam results with minimal preparation. Got several degrees, I had a scholarship, a sponsorship through my employer, and I've enjoyed a succesful professional career for many years now.
I was never diagnosed with ASD or ADHD but I certainly have traits of both which took me years to realise. I'm great at masking and I have a very rich social life, you couldn't tell, but I'm a bit of an imposter copying other people's social behaviours. I get overstimulated and exhausted easily. I find mutisensory environment overwhelming. I have always suffered from anxiety. I thrive in routine, cleanliness and I like predictability, patterns and being in control of the situation. At the same time I am the person who works best between 11pm and 3am and in those 4 hours I can produce work in one night that other people would take a week to produce. I have always been this way, my brain is able to absorb and analyse a huge amount of information very quickly.
My father is definitely autistic and the most intelligent person I've ever known, extremely gifted. He is also the most difficult person to be around and we are NC. He is gifted in maths, science, geography and politics in particular, but has phenomenal general knowledge.
I am now watching my DS who isn't even in primary school yet and is multilingual, studies books about human body and can name most of the bones (?!), never shuts up with the 'why' questions, builds things which look as if they were built by an 8yo and recently his brain exploded and he's telling us stories about the things that happened when he was just over 12mo which he somehow remembers - they are correct and we never talked to him about them in between or gave him any prompts. He is fabulous but also very much like me in many ways and this can be difficult. No idea what he's going to be like but he's certainly above average in many ways.
