It seems that the Twitter post "lunching" does not relate to a maintenance report feedback to a public flat house. It is not clear what the post is referring to, as it is not a specific word or phrase related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any other category. The "explanation" field provides a brief explanation for why the post is not related to the topic.
