The given Twitter post does not relate to a maintenance report feedback to public flat house in Singapore. The post simply mentions "island life" and "Sentosa Island" which are locations in Singapore, but there is no mention of any maintenance issues or feedback related to public housing. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a short explanation that this is not a relevant post.
