Curate, connect, and discover
Cale is so touch starved that when someone gives him a hug, he legitimately doesn't know what he needs to do with his hands. So he just stands there, awkwardly waiting until the person lets him go.
It's painful to watch how he gets stiff as a board when someone touches him by surprise. It's obvious to everyone how he prepared himself for the pain that never comes. The fact that he looks confused is even worse.
So now, after a family meeting, they decided that they would start with little gestures like pats on the shoulder and high fives. And then maybe fast hugs from the kids.
