- Inexplicable social exhaustion
- Superficiality [or affectation] of interactions (or alternatively, a complete withdrawal of interaction)
- Regular 'personality clashes' which are based on misunderstandings over intent (which can be caused by blunt/directness and eventually manifests itself as defensiveness) [NB. 'Misunderstandings' are a major part of being an undiagnosed adult, I guess this is more of a expression of a trait rather than a trait]
- Vast unknown gaps in social interaction that are patently obvious to NTs but we're oblivious of (can manifest as rambling monologues, inappropriate timing as you state, but also can be overcompensated for by being oversensitive to social interactions creating a whole bunch of different characteristics like social phobia etc - this is very dependant on the type of life you've lead and the conditioning from it, some people are fortunate to have been surrounded by understanding and forgiving types, some are not - i.e. we aren't all grumps or all gorgeous, it is highly dependant on our role models and the environments we have developed and lived in)
- Reduced tolerance for personal eccentricities and rampant control freakery (in trying to avoid issues arising, we could potentially become rather uptight - an inability to fit into the crowd affects people differently, dependant on culture, e.g. I often see the American users more likely to be more strident about this than a UK person like myself)
Unfortunately, specific traits are very hard to define because living with an unknown 'illness' ultimately creates a level of conditioning, the depth of which can be incredibly subjective. Some people fit the mould, others are massively distorted. Hence difficulties in getting diagnosed as an adult precisely.
Some of the traits are not clear because they are actual gaps in our understanding, even though we may have created a poorly derived fix for them, we potentially don't see them for what they are. When I was diagnosed (as an adult) I offered my wife a divorce because she hadn't married an autistic man and I felt this was unfair. This, apparently, was a very autistic thing to say
