I am really sorry that happened to you, particularly at that vulnerable moment.
I hope you have found some measure of peace since that event. I still miss my dad, even though it has been 13 years since he passed.
My dad passed in 2008, so it has been a while. I got over Dad’s passing better than the extreme cruelty of TSA chick. We’ve had other negative experiences at LAX with TSA. It’s like they’re trained on how to be abusive. Maybe they are.
