What You Don't See

 There are times when what we see right there in front of us tells a simple and clear story. The evidence in front of us is so certain, so obvious, it is easy to understand.

But, it’s always a good idea to look a little further. It might be the things you haven’t seen – that are very much a part of the story – that will complete the picture, and give you real understanding.  

Sometimes the hidden things, the ones you don’t see, make all the difference.
