For me it's well pretty much what has been said..I live 24/7 but in some cases I have to have limited decisions made that Sir isn't present for. (The reality being we have to work). I am not always able to have Him around to ask what I should wear, eat, drink, if I really want dessert or not..
That I think is the time in which I have temporary power (that and in dealing with our child). However when Sir is home, He has complete power. I can always say no, but those are the days I'm going the right way for a smart bottom.
