Lyric discussion by vinyldude 

I think the song could be from the point of view of a lover who does not know that her workaholic partner is actually having an affair. She is truly in love with/desires him but can't understand the hours he pours into his work. Even when she calls he 'denies' her wishes to return soon, sometimes refusing to pick up ('call me back') and showing little emotion about the situation ('robot'). Or, perhaps the 'When you gonna come home?' is more of a desperate plea where the woman actually knows he's cheating, but hopes they can reconcile. This is evident since she waits up with the lights on ... sounds sadly hopeful that one day he'll return to her.

i think you're reading too much into it... just sounds like a sexually frustrated wife living with her husband that appears to have lost all interest in her (or anyone for that matter). Dude's life completely revolves around work and probably staying out late at bars drinking himself stupid.

although i guess "go to work" could be interpreted as cheating... i just dont see calling someone a robot being related to that.
