Looking at something from only one angle such as the top part of this leaf leaves out the entire back view. And if you can only look at something from one angle you are not seeing the big picture.
We just had a big shake up at work where the director's changed the entire schedules of the employees who work at our company. Of course they are only going to give a number of reasons for such a drastic change, maybe one or two perspectives without giving the entire big picture. It doesn't help the staff who want to see why something like this that affects them so much could happen and they can only see a partial picture.
I think those might the harder lessons in life to learn.
