I had an NT brother and sister. Same story. They could do no wrong.
From the time I was born to the time my parents each died I was the lesser, excluded, much less gven, much less loved. Isnt it the way of humanity to push aside and abandon those who are perceived as different since they represent weakness in the species?(even if they are not truly weak)
People love to think we are so evolved and civilized but I don't believe we have evolved, just concealed our horribleness better.
