I tend to drop it unintroduced because I don’t see how that mentoning something like that wouldn’t be random. It is like saying… by the way. I miss a foot. Most conversations dont deal about having feet so there wouldn’t be a lead towards such a thing either. But I say a lot of random things anyway so I just pop something like that in there. Maybe you could write a short text with the positive sides of your Asperger’s but mentioning that it comes with a couple of quirky things that the other person should know about? Being positive about something like that makes others view you in a positive way. Glass half full people are attractive and always feel less problematic to others than glass half empty people.
