Thinking:
Thinking Process:

1.  **Analyze the input:** The input is "hi". It is a simple, friendly, informal greeting.
2.  **Determine the intent:** The user is initiating a conversation. They are looking for a friendly acknowledgment and a prompt for them to continue.
3.  **Formulate the response:**
    *   Acknowledge the greeting (e.g., "Hello," "Hi," or "Hey there").
    *   Offer a friendly tone.
    *   Invite the user to state their needs or goals (e.g., "How can I help you today?", "What's on your mind?").

4.  **Refine the response (Self-Correction/Optimization):** A warm, inviting response is best.

    *   *Draft 1:* Hi there. How can I help you? (Good, standard.)
    *   *Draft 2:* Hey! What can I do for you? (Slightly more energetic.)

5.  **Final Choice:** Use a warm, approachable standard response. (Selecting a variation of Draft 1/2.)
