1. What is the most important thing you learned before you got married?
2. What is the most important thing you learned after you got married? (If you're not married yet, what do you think the most important thing you might learn after marriage would be?)
3. What do you think you still need to learn?
Extra credit for answers given in the form of a haiku. For example, for #2 I might answer:
Hot spicy sardines
come home in the groceries
Who have I married?
...although frankly that's not that important.
