My wife is a victim of a school shooting in the mid 90's. while she wasn't hit or injured by the shooter, she fully carries the trauma each day of someone getting shot 2 classes away from where she was, jumping out of a window and having scars still where the shattered glass cut her and the chaos and madness that happened in the next few seconds and for MONTHS after.
Prior to our kids going to school, she shared with them her experience, What to expect, where to hide, how to get out, etc...everything she had learned about that day and things she has thought about for DECADES she would have done differently that day.
Watching your wife have this conversation with your 6 year olds as they leave for school for the first time is HEARTBREAKING, INFURIATING and SICKENING.
