Yeah, that makes sense, and can totally empathize with them for that. I love independent women though, and love a career oriented woman, so I can't complain. I had just hoped it was going to be equal, she'd consider the situation and help out a bit. It's not entirely her fault though, I add to the entropy of our marriage just as much, if not more.
There is a huge amount of social pressure on women to grin and pretend that to be the case. My wife and I work in the same profession and are similarly busy. But she gets 10x as much flak for the same things (blowing off parent-teacher conferences, etc) than I do.
