I've noticed that everything in my life is sudden. I don't have gradual changes in situation. If things are going right, suddenly, they all go wrong. If they're going wrong, they suddenly go right. Often with no explanation or discernable mechanism. They just happen. It's neet. One can view it as being gradual, beacuse of the long periods of seeming inactivity/ no change. Which is seeming... it's just that everything takes time getting set up quietly, so that when they all move in unision to completely reverse the way things are going. so if you're paying attention, you could claim that it's not sudden, but it takes a very wise outside perspective, or 20/20 hindsight.
