Or so you think. Humans aren't any good at that whole "self-awareness" thing.

Even the "no empathy" sociopaths can spend decades thinking that they're perfectly normal, everyone is like them, and people just pretend to be sad and grieving at the funerals because that's some kind of established convention and breaking it would be very rude.

What I'm saying is: maybe you just think you don't show any signs of autism - because you think your experience is "normal", and you think that everyone has the same struggles as you do, even when it isn't true.

Or maybe you genuinely aren't autistic at all! It's just very, very hard to say at a glance.
