List three of your greatest talents. Don't try to be modest :)
Talk about your best friend.
Do you have a sibling? If so, what is your relationship like with them? If not, what do you imagine it would be like?
Are you patient? Talk about your boiling point.
Talk about a time you have been unlucky in love or embarrassed.
Recount a story of when you did something against the law/generally bad and had loads of fun.
Within your close group of friends, talk about the dynamics. Who is the "mother" figure? Which role do you play?
Talk about a time that you felt invisible -- like you weren't even there.
