It seems that the post does not relate to a maintenance report feedback to public flat house. The phrase "happen know whose building" is not specific enough to indicate a particular issue or location, and does not provide any context that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because there is no specific type of feedback or issue mentioned in the post. The "explanation" field is left blank because there is no additional information to provide beyond the initial assessment that the post is not related to public housing or maintenance report feedback.
