Well, I'll share this as my answer.
Yesterday at Costco/work I saw maybe the most touching thing:
2 brothers, 1 looked 16ish with somewhat of a severe case of autism. Older brother young adult. That brother held his hand, hugged, held face, kissed forehead, praised, and just plain protected his brother. All that was missing was soft music. It was absolutely the greatest thing I've seen in years. And it wasn't like big brother was just helping, it was a bond. I was speechless. I don't assume to know all the younger brother has to go through, its probably very difficult, but I'm honestly jealous of that kind of bond. My family loves through works of service. Besides my mother, its very cold and very little awkward affection. What I saw was the purest form of brotherly intimacy. If I'm lonely for any reason, that's it right there. I even wondered if there is a program to get paired with a "mentor" who gives that warm attention...in a perfect world, right
