"How many of your friendships have lasted more than ten years? Which of your current friends do you feel will still be important more than ten years from now?"
I had to pick a question that would redeem me after saying I would ditch my best friend for a million dollars (I always remove "spouse" from "best friend" questions --they may be your best friend but are disqualified because they are also your spouse...) My picking the money over the friendship isn't a lack of loyalty...just honesty and practicality...you'd be hard-pressed to find someone that sustains friendships as long as I do.
My three best friendships have all lasted significantly longer than 10 years. I have been friends with JustRose and Liz for 31 years and my friend N in OBX for 16 years. I feel all of them will be just as important in 10 years as the likelihood of someone forking over 1,000,000 to kick them to the curb is slim.
