They laugh at him and his antics. And he laughed along. But no one saw him cry but one man.
They get worried when he got sick or hurt. He laughed again, saying he isn't going to let anything drag him down. But no one saw him struggle to breathe or walk but one friend.
They tell him that if he wanted to talk, they're open. He laughed in gratitude telling them that he'd keep that in mind. But no one had him open up to them except for one child.
They only ever saw him laugh. And eventually, his laughter became his lies.
