Please provide me with context! "What's the matter with them?" is a question that requires more information to answer meaningfully. To help me understand what you're asking, please tell me:
- Who are "them"? Are you referring to people, animals, objects, or something else? Be specific!
- What is the situation? What are they doing, or not doing, that concerns you?
- What kind of answer are you looking for? Are you looking for a medical diagnosis, a psychological explanation, a technical solution, or something else?
The more detail you give me, the better I can understand your question and provide a helpful response.
