David was an attractive, dark haired, dark eyed, 13 year old, well fed boy, when he came to stay with us.
He was bussed to a school with 3 teachers to 7 student, ratio.
Soon, we found him to be mean, conniving, towards others, and animals., turning anything he picked up, into a weapon of some sort.
When David returned from a Xmas family visit and I asked him what his TWIN SISTER got for Christmas, and he said ........HE DIDN'T KNOW!!!!!!!!!!!!
Even if you hate her......... you still KNOW WHAT SHE GOT. It's either bigger or smaller or cheaper or more expensive.......etc
We concluded that since David had no feelings, even for his twin sister, then he had no feelings for anyone.
That is too dangerous a situation to be around.
David left our home after only 2 months, for a higher level of care, and we all collectively, and individually breathed a sigh of relief.
