The given Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The post is about a person's pride in their second son marching in a parade today, and their duty as an honour guard for a flag float. It does not mention any issues or concerns related to maintenance or infrastructure in public housing. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a brief explanation of why the post is not related to the requested topic.
