I personally am emotionally frustrated that we live in a country, that we have come to a point that our youngest generation will not feel safe, particularly in a place that they should feel the most safe.....
The place every child, and every adult, should feel safest is
home. "A man's home is his castle", "Be it ever so humble, there's no place like home", etc.
Not school.
So, make reason the master of your mind. Jettison the frustration, face life with your eyes open, and remember this:
There are bad people in this world.
There are good people in this world.
There are bad people with guns.
There are good people with guns.
The only thing which will stop a bad person with a gun, is a good person with a gun.
