General Discussion

I certainly did.
More interested in introspective thinking, working out how physical things worked - wind up clocks just begging to be dismantled - and other humans were just mere shadows.

Sailed through school and 6 years of University because, well, something to do while NOT communicating with others.

Then - fortunately for me - I went to work as a teacher.
Figured out I'd better learn to communicate with others. Took some effort, but that opened up a whole new world for me.

Still prefer my own company.
Stil prefer physical devices over people.
Cars and computers, amongst many other things, are my reliable and predictable 'friends'.
People on the whole are less reliable, less predictable.

Wife is the opposite, comes alive only when in a crowd.

News flash! We are all NOT the same. 'Different' doesn't instantly deserve an 'autism' or 'ADHD' diagnosis.

My suggestion:
Accept yourself and others as you find them.
Forget self diagnosis, forget labelling yourself and others, accept we are all on some 'spectrum' or other.
