Personally, I wouldn't say the dividing line was between "gifted" and "not-gifted", I'd say it was probably between "struggles socially" and "does not struggle socially".
My db was very obviously gifted. So was my nephew. Top marks in everything, composed and played their own music, db represented his county at his sport, dn is just off to one of the top conservatoires in the world, having had an equal choice of doing STEM subjects at a prestigious university. Db is a successful academic.
But they were both very ordinary children: happy, giggly, fitted in well wherever they went, db was one of four and didn't seem the odd one out in any way.
On the other hand, I have seen many examples of the quirks commonly associated with gifted children in children who turned out (once they got to university) not to be particularly gifted academically.
Could you explain, OP, what makes your experience so different that you have to ask yourself what it would be like to have a more "normal" one?
