Except you didn't say that kids should be the most important. You said the adult's lives should REVOLVE around the kids...
To me, that means EVERYTHING gets put aside for kids. "Sorry boss, I can't go to that convention because Billy has a band recital." "Sorry, Bob, I can't go out for drinks because I need to tuck Sally in at night." Don't get me wrong, DW and I try to be at all the kids' events, we do what we can to give them opportunities to succeed or just experience different parts of life. We do sacrifice our "lives" sometimes to accomplish this. I'm not going to fault parents who don't do this though or say they should do so.
DW and the kids (I'd hate to have to pick which is more important) ARE the most important things to me. But I'm still able to do things on my own (at least with enough planning).
