It seems that the provided Twitter post does not mention any information related to a maintenance report feedback for a public flat house in Singapore. The term "greenwood sanctuary" and "admiralty singapore" do not seem to be associated with any specific maintenance or housing-related issues. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the post does not relate to the given category.
