of course there are situations where simply taking responsibility for something can help, but i don't see that in the situation described. if my wife is scheduling to many activities for the children, how can i take over when i simply want there to be less activities.
in other words if my wife does something that in my opinion simply should not be done, how can i stop her, other than sharing my feelings about it? how can i take ownership of the kids activities other than replacing them with other activities. or what do i do when i am at work while this happens? and working until 2am at night? how am i supposed to react other than saying, please don't do that?
