It seems that the Twitter post does not relate to a maintenance report feedback to a public flat house. The post simply mentions the word "leaf" without any context or content related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of feedback provided in this case. The "explanation" field contains a brief explanation of why the post does not match the given criteria.
