    ]

It seems that the Twitter post does not mention anything related to maintenance report feedback for public flat houses. The phrase "nobody really cares" suggests that the speaker is expressing a negative emotion, and the use of the word "miserable" reinforces this interpretation. Additionally, the mention of "happy Singapore" seems to be an unrelated thought or observation, and does not provide any clues about the post's relevance to maintenance report feedback. Therefore, the answer is that the post does not relate to this topic.
