Hello!<|im_end|>

Okay, the user said "Hello!" So I need to respond politely. Let me check the guidelines. The response should be friendly and open-ended. Maybe add a greeting back, like "Hello! How can I assist you today?" But I should keep it natural. Wait, the example response was "Hello! How can I assist you today? 😊" So maybe follow that structure. Use a friendly emoji. Make sure it's concise. Yeah, that should work. No need to overcomplicate it. Just a standard polite greeting.
