Here's one social rule that seems almost kind of cruelly ironic, which I don't totally agree with but have learned the hard way:
When you "come out of the Aspie closet" and tell someone that you have Aspergers (and I mean someone who you've known for several months or years), the person doesn't know what Aspergers is and so you explain it, then you get the seemingly flippant response "Oh, well...we all have our challenges to deal with in life." - DO NOT debate them or give them the "how dare you" response that they are trivializing your condition - they didn't know what it was to begin with - it's not like a revelation about past sexual abuse or that your brother was killed by a drunk driver, in which case their flippant response would be unacceptable.
I challenged somebody on this response once, and he basically told me, in a patronizing sort of way, that my indignant response would only lead people to think I'm even more strange, and that I'm inviting a "pity party". His response was basically for me to "take the hint" and not debate a subject further that he did not feel comfortable bringing out in the open. Hence the irony, that we are tempted to set people right on the seriousness of Aspergers.
