I'm having a hard time thinking of anything good, but here's the best I've got:
1. When you get married/got married, will you/did you change your name to your H's last name? (If married, how long did it take).
2. If you did/will change your name, did you have any hesitations? If you didn't change it, why not?
3. Do you prefer "Ms." or "Mrs."?
Please feel free to add more questions!
