It seems that the Twitter post you provided does not relate to a maintenance report feedback for public flat houses in Singapore. The post mentions "nature calling" and "pulau ubin", which suggests that it may be a reference to a natural attraction or a travel destination, rather than a maintenance issue. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to maintenance report feedback.
