How nice if we are born with batteries like the Eveready Bunny that goes on and on and on. We will never ran out of batteries that way.
However, we are not. We constantly need something to charge us to make us move again. It can be some happy events or some really great friend. Otherwise, we will go flat, sad and just plain dull. Often, we don't find these and we live life like a bunny without batteries. We just stood still and not moving.
Then again, life is not that bad either. At least there are things that can jolt us back to life.
