The given Twitter post does not seem to relate to a maintenance report feedback for a public flat house. The post is a throwback to a previous post from 15th February 2020, where the author welcomed a fairy into their home and expressed gratitude for the opportunity to attend an air show. The post does not mention any facilities or infrastructure related to public housing, nor does it contain any language that suggests a maintenance report or complaint. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a short explanation indicating that the post is not related to maintenance report feedback for public flat house.
