How dare anyone, tell a mother, not to cry behind the death of her son? "When I Grow Up" Documentary speaks with three mothers who have lost their sons to senseless gun violence; their memories of their sons and all of the things they still wanted to do in life was shared. It is a crazy world we are living in now. Be it 7, 17, 27, 37 years old, death cared nothing about a number....but there was still so much life to live.
