The distance between the metaphoric A and B is often a very long arduous journey. The A point being when hubby tells me that something I'm doing is wrong and the B point being me accepting that he might be right. It happens on rare occasions - that he's right that is.
Along that journey there are many occasions when again, metaphorically speaking, that I want to stab him. I don't of course, only in my head - because that sentence would be too much on top of the marriage sentence I'm already serving.
