When I read that people with Asperger's have a hard time with sarcasm, I thought "wait a minute....I love sarcasm! I use it myself!" I can usually tell when people are being sarcastic, although there are times when what the person just said sounds reasonable. Even then, I don't take what they say at face value, I just need to stop for a second and try to process what was said ("wait....are you being sarcastic?"). This becomes even harder online, without facial cues and tone of voice to help out. On another website I belong to, there was a discussion about "What was the last documentary you watched?". My wife posted "This Is Spinal Tap", which I immediately recognized as being sarcastic. But then someone else posted "The Blair Witch Project", and based on this person's posting history (he's a little on the slow side), I replied with "I can't tell if you're messing with us or if you actually think that was a documentary...?". Based on how the discussion went from there, I'm still not 100% convinced he doesn't believe it's an actual documentary.
