It seems that the Twitter post "happy days singapore" does not relate to a maintenance report feedback to a public flat house. It is not a complaint or feedback about a broken facility, inconvenience, or any other issue related to public housing. Therefore, the answer is { "relatedness": False, "type": "none", "explanation": "This is not related to public housing or maintenance issues." }.
