What does "obey" mean in "righteous women are devoutly obedient" in Qur'an 4:34?

Can someone please define the word "obey" in the context of this verse. > http://quran.com/4/34 Men are in charge of women by [right of] what > Allah has given one over the other and what they spend [for > maintenance] from their wealth. So righteous women are devoutly > obedient, guarding in [the husband's] absence what Allah would have > them guard. But those [wives] from whom you fear arrogance - [first] > advise them; [then if they persist], forsake them in bed; and > [finally], strike them. But if they obey you [once more], seek no > means against them. Indeed, Allah is ever Exalted and Grand. Any real world examples what it means for a wife to be obedient?
I can't think of any examples to help me clarify this.
