He hated the holidays because he lost loved ones. Everyone gets socially awkward copes differently. He just remembered the good times. While others got drunk or belittled others to feel secure about themselves.
He couldn't honor their death everyone cracked beers at the cemetery.
He went on his own time and randomly. He enjoyed the quiet remembering loved ones praying to God for peace and closure. Preferred to be alone than be around people; who tried to tell him, how to act, or feel. It was insulting to be around people; who thought less of him. Ignored him because the focused on material possessions than intellect.
