seriously:
with what person do you have the most important relationship in your life ? and why ?
I think 'do you live with your mother ?' gets top billing. Asking about that relationship with mom is also good.

what is the best decision you ever made ?
on which side do you 'dress' ?
sorry, I can't do it seriously...

when in doubt...do without
