It seems that the Twitter post "street life singapore" does not relate to a maintenance report feedback to public flat house. It is not specific to any particular issue or facility, and does not appear to be a complaint or feedback of any kind. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance reports."
