It seems that the post you provided does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post appears to be a message from a parent to their child, expressing the importance of marking one's territory and leaving the world a better place. Therefore, the post does not fit into any of the categories I mentioned earlier.
