Your theory seems insightful to me. I think the opposite holds true, its not just the bad things that teach us lessons, but the good as well. The only place I differ with what you said is that our souls or whatever you want to call it decided...I belive there is a divine presence that gives us these lessons to learn...if we react well then perhaps it is the last time we need to face that lesson. If we react poorly then we need to keep facing the same lessons over and over until we get it right. Love you dear, thank you for sharing your thoughts.
