It’s sad but true that there are still families that shut down a little boy’s emotional experience of the world, believing that to be sensitive to feelings is “unmanly.” Or he may actually have emotional memory but doesn’t recognize it as such or doesn’t have a vocabulary for it. And one of the characteristics of post-traumatic stress disorder can be dissociation from feelings.

I wish you well.
