What a touching thread. Rotten childhoods sure can mess a person up but it is amazing that little things like unexpected kindnesses (like happened with those kids) can go so far to change a person's behavior. My H definitely falls into the incredibly dense category frequently and also responds to direct suggestions if they are repeated 5-10 times. I used to think his density was at least partly on purpose but now I think he just doesn't get it and I've gotten more patient with him and his "impairments".
