+# Question 3: What's Their Mental State at This Moment?
+
+**Understand the emotional context for design decisions**
+
+---
+
+## The Question
+
+```
+Agent: "When they find your solution, how are they feeling?
+
+        Think about:
+        - What just happened? (trigger moment)
+        - What are they hoping for?
+        - What are they worried about?"
+```
+
+---
+
+## Why This Matters
+
+Mental state determines:
+
+- Tone of content
+- Complexity of interface
+- Type of features needed
+- What NOT to do
+
+**Design for the human, not just the task.**
+
+---
+
+## Example: Dog Week
+
+```
+Designer: "Just had another fight about who walks the dog.
+           Tired of nagging. Want a system that works without intervention.
+           Worried about adding more complexity to family life."
+```
+
+**Design implications:**
+
+- Tone: Empathetic, not preachy
+- Interface: Simple, not complex
+- Features: Automated accountability, not more work
+- Avoid: Notifications that feel like nagging
+
+---
+
+## What Agent Captures
+
+```
+MENTAL STATE:
+- Trigger: Just had family fight
+- Feeling: Tired, frustrated
+- Hope: System that works without intervention
+- Fear: Adding more complexity
+
+DESIGN IMPLICATIONS:
+- Keep it simple
+- Automate accountability
+- Gentle, not pushy
+- No nagging-style notifications
+```
