This is a cross post off of E about being able to answer these questions about your FI:
Who are your mate’s two closest friends?
What is your mate’s fondest dream in life?
Who is your mate’s least favorite relative?
What is your mate’s basic philosophy of life?
What are your mate’s three favorite movies?
What are your mate’s three most special times in their life?
What are your mate’s current major worries?
What would your mate do if he won the lottery?
I thought it was kind of interesting. Although, I don't agree with the whole bit about it determining if your marriage will work or not. Anyways, answer them if you want to!
