My problem is the opposite way round. People don't realise that I am "ret*d"*, socially and emotionally, in the French sense "etre en ret*d", late, i.e. a development delay.
People tend not to realise I'm Aspie, but they perhaps realise something's a little 'off', like I can launch into monologues (although I don't talk in monotone, I've worked in television and radio journalism and I've had voice training in reading news scripts) and persevere and obsess about stuff, and I'm quite blunt and outspoken, and a former boss called me "rude, abrupt and abrasive".
I'm fairly good at 'pretending to be normal' by now, after all, I've had 40 years of practice. They judge me as having some kind of character flaws, or think I'm a bit eccentric, rather than realise I'm really, y'know, different.
