How did he or she propose?
Did you say yes?
If you did the proposing, how did you do it? Was your proposal accepted?
Have you ever turned down a proposal? If so, why? How did he or she react?
ETA: If you've never been proposed to, do you ever daydream about how you would like it to happen?
Inspired by my boyfriend getting drunk and telling me exactly how he plans to propose to me if/when he does
