It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The term "blood is thicker than water" and "cousinsquad" suggest a personal relationship or bond, while "cavern" and "horsecity" are not related to maintenance or public housing. Therefore, the answer is "relatedness": False, and the type is "none".
