perfect exmple..... our then neighbor worked at the twin towers . he had a meeting on the top floor with his company he worked for ( i have no idea what his job was- rich? from that job? wouldnt have known it) it was a beautiful day that day and just decided he would not go in. something held him back.. he was traumatised emotionally for being alive...when his friends from work all died.. he never spoke about it tho.. never.
