Henix - As I've never met you, I can't say what impression you actually make, I'm just speaking about people with AS, in general. Excluding professionals and people with personal/family experience of AS, people may see you as different, but not be able to put their finger on it. I think most people have heard of autism (and think they have a fair idea what this is, but are often way off mark) and less people will have heard of AS, although from experience, most people say they've at least heard of it. Many of those who know something about it often have an image of what they think someone with AS is like, which may be fairly accurate for some people with AS, but not the majority. If you're close to that image, they might guess, otherwise I doubt it.
When my daughter's speech & language therapist met her a few weeks ago, for the first time, he suspected it within 30 mins, but he's an experienced professional who specialises in AS. If I tell an acquaintance that she probably has AS, they'll usually say, 'Really, but she's so chatty and outgoing. It must be very mild'. They've no idea her extroversion has no bearing on the diagnosis or severity of the AS. Actually, she's much more outgoing than average, which is significant, but no-one seems to be aware of that fact. Neither was I until I started reading about it less than a year ago and quickly worked out that I also fit the criteria. No-one appears to have suspected AS with me, just that I was unusual. Although during a personnel discussion at work, where it was mentioned that a temp possibly had undiagnosed AS (someone close to stereotype), I got a few strange looks, as if they suspected something about me, that I wasn't aware of.
