The Hard Truth is: Most parents are very diplomatic and treat everyone the same. But some do not. To be clear, every parent has a favorite. Sometimes the favorite changes over time, or there will be a favored one in a certain situation. Your parents make it so obvious. I’d be hurt, too.

Your sister sounds too “perfect”. You may be labeled as “difficult”. Your Asperger’s son may also be labeled “difficult”. And the fact that the parents are willing to move into a “perfect” home with five kids?? Something is going on. That’s just nutty. I hope that the “perfect” family scene dissolves into base normalcy for the parents!

I would either scare them by packing your bags and saying, “Well, HERE we are!!” and make believe like you’re both staying at her house (“Until I get back on my feet” LOL). Or, just move across the country. Then have THEM see YOU! That may never happen, by the way, but at least you’d have PEACE.
