Life vs Dynamic

A question about life getting in the way of the needs of the dynamic made me tilt my head to the side and go "huh?"  I'm pretty sure my confusion stems from the inability to separate our dynamic from our lives therefore I lack understanding of what type of life event gets in the way of the needs of our dynamic.  We have a basic need and that is to maintain our proper places, how we do that is pretty flexible so nothing has come up that veers us off that path. Even on the occasions that I need to take a bit more innovative than I'm used to or frankly comfortable with we both see it as service to him so even those times aren't going against our dynamic's needs.

So I wonder how others classify various life events and their effect on their dynamics. For that matter I also wonder how their dynamics are defined in the first place because even the same words when used in a different context can take on very different meanings.
