Everyone has flaws so I wouldn't waste time on that. I think you can find out more from a person if it's a down-to-earth and fun conversation. Depending on how much time we'd have, I'd try to ask these questions:
1. What’s the most adventurous thing you’ve ever done?
2. If you had three wishes, what would they be?
3. What are you most passionate about?
4. What do you consider your 3 best characteristics?
5. When are you the happiest?
6. Who are a few of your favorite musicians?
7. Where have you traveled?
8. What’s the first thing you notice about a person?
9. What's your best talent?
10. What are the most important qualities you’re looking for in a relationship?
