  I apologize, but the provided Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The post appears to be a statement about the diversity of audiences at opera houses around the world, and does not mention any specific issues or concerns related to maintenance or public housing.

Therefore, the answer to your question can be represented in JSON format as follows:

{
"relatedness": False,
"type": "general",
"explanation": ["This post is not related to maintenance report feedback for public flat houses."]
