1. People with perfect vision: When it's dark outside and you look at a light (like a street lamp) do you see lines around the light? Like a halo or a starburst? Or do you just see the light?
2. People who need vision correction: Do you remember a time when you could see perfectly? What was your first clue that you weren't seeing things like you were supposed to?
3. At a restaurant, would you prefer to ask for your check when you're ready, or have them set it on the table at the beginning of the meal?
4. What are your plans for this evening?
