I have two boys that are both mildy aspergers. The oldest one showed no melodrama at all. He is now opening up a little more emotionally in his teens which is actually good. But the youngest especially when corrected, would take it overboard and say he's the worse kid ever etc. I would give him the "look" to remind him I didn't think much of his melodrama. I would gently tell him I disagreed with his opinion and let it go. I have tried ignoring this behavior so as not to give him the negative attention I think he wants from this behavior. He doesn't do it often, and I feel with all the moments of cuddling and loving we share, he won't have any long term effects from this. It isn't a good character trait that we as a family appreciate, but we're not real concerned about it as his self esteem seems to be okay elsewhere.
