He was onto new things missing his old life. Trying to go forward not go back. Closed off seen as a hard *** but once he opened up. Always focused on work no time to show emotions. Being social was easy he had nothing to hide.  Everyone else was closed off and defensive threatened, by his honesty it made him feel bad for telling the truth.
He sat in his room alone with comfort. Going in public was unsettling in a crowd. Kept to himself minded his own.
