I had a friend go through a terrible tragedy where his son darted out into the road on a scooter and his wife was driving the car that the child darted in front of. There was no possible reaction time. They clung to each other as the storm of pain washed over them and continues to this day years later. Facebook is especially painful because of the reminders that pop up and renew the newness of the loss. Sometimes people might blame each other but it's a choice to hold tight to each other instead.
