I once laid down on the driveway with the daughter of my boyfriend's sister, who has Angelman's Syndrome. His whole family was BBQing over at his other sister's family's home and it was her way of protesting when it was time to go home... she was having a temper tantrum, which is not in the least like when "normal" kids have temper tantrums.
The entire family looked at me like I'd lost my mind. But Sierra calmed down, snuggled up to me, we got up and I loaded her into the truck and they went home. And the family STILL thought I was a nut.
Broke up with him. Of course.
