I've only ever heard it used for a lover or spouse.. in anime, dramas and songs.. except.. Aya Ueto's song Kansho.. she asks "Anata Dare Nano" which I roughly translated as 'Who Are You' ._. thats the only part of the song I could translate at the time using dictionaries and probably got it wrong. xD and I failed at finding Japanese song translations on the net at the time.. Being new to the computer sucked ._.,
