Give someone enough prompting that they require support to deal with a situation and they will begin to believe it before it has even happened.

I always cry at something in LOTR and I've read that for years, I cried at Bambi when I was little and at the end of Shanghai Triad as an adult. I'm good with crying at fiction. But traumatised, no. I can go back and watch or read those again and know I'll have an emotional response. And none of that sets you up 100% to cope with having a parent/spouse/friend die. Counselling or no, death is fact.
