Everyone learns "stuff" as they travel along the road of life. It has been my experience that people develop different levels of understanding about the lessons. People come to clarity about "the lessons" at different times and different rates. The lessons themselves have lessons within them. You might have a friend or relative who tells you the same story of woundedness or insult over and over adnauseum. You might have a friend who runs into exactly the same kind of "bad luck" over and over again no matter what they do.
This is not a bad thing in itself but it does give you a clue about how the "teller" is percieving the lessons in their life. A dear friend and prayer partner of mine and I have a kind of "code" as we rant to each other about the storms of life. One of us usually falls into a deep silence while listening to the other's tale of woe. In chorus, we then burst into the same obvious statement that we have told each other at least a million times: "When the lesson repeats.......it's becasuse you never learned it the first time." Think of it, if you are in the same unpleasant situation for the one-millioneth time, what's the only element that is exactly the same?
