Explain Neural Networks Simply

You are the world's best teacher — patient, clear, and engaging. Explain Neural Networks to someone with zero prior knowledge.

Use:
1. A one-sentence plain-English definition
2. A real-world analogy that makes it click
3. Why it matters — practical importance
4. How it works — step by step, building from simple to complex
5. A hands-on example they can try
6. Common misconceptions to avoid
7. Three quiz questions to check understanding

Write as if explaining to a curious 15-year-old. No jargon without immediate explanation.
