hiding to cry & Ok to lie!

I lie. I admit it. Call it over protection. Call it shielding.  Call it self preservation. I have no words to describe the most awful hatred and violence happening around the world.  There are no justifications, no purpose, or ways to make it better.
Tears pour down my cheeks while reading or thinking about those victims, refugees, immigrants and others who suffer at the hands of terrorists or other humans all around the world. 
Do I have to explain these events to Jake.  A child who believes everything will be okay if we just treat others how we want to be treated.  A child who perseverates on drama, big emotions and yucky stuff.  A child who feels our emotions ten times deeper than your average bear.  
Our standard rule of thumb is "garbage in, garbage out"!  Does he really need to know that other people join groups that like to end the lives of people just like us?  Does he need to live in fear and add to his already paralyzing anxiety? 
How do you teach a literal thinker with limited comprehension ability, that some people think they have the right to kill people? 
How will it help him to know about hate groups like ISIS or KKK?
He does need to know that there is awfulness in the world, but when's the time? How do you determine the age when he can "handle it"?
I don't want to tell Jake.  
I don't think I will.  
For now, I will continue to read the paper in private, switch off the news and protect our Super Hero. 
I will always be hiding to cry.
