How to Survive in the Line of Fire

I want to write about this now while it's still fresh in my mind...might be good for the germ of a future story.

I was riding BART and reading Pontoon, by Garrison Keillor (which is making me nostalgic and thinking a lot since it has a mother dying plus a woman going home to MN for her wedding...). Also the book review on this link has Keillor with a shaggy graying beard.

I was late (it was after 9 am) so I didn't have a seatmate for most of the trip until Civic Center when a woman sat down next to me.
When I was packing up Pontoon to get off at Montgomery, I see that my seatmate is reading a little card that is titled "How to Survive in the Line of Fire" and has all of these tips and diagrams for trying to stay out of harm's way in that situation.
It looked like something from those Worst Case Scenario Survival Handbooks, and after googling around, I am pretty sure it was.

It made me wonder why she has this at this time. Does she have the whole set and she reads one each BART ride to be prepared? They are meant to be humorous but this one was a bit surprising to see she was reading it specifically.
When I got up I accidentally jostled her and all this colored paper she had fell on the floor. I helped her pick some of it up. It looks like she is making a card for someone - she also had colored pencils...
Is she making a card for someone going into the Army? Is it just a joke card? The tips were so realistic that it seems it wouldn't be a joke.
She was in her thirties or early forties, long brown hair curly in ponytail. She was grateful for me trying to pick up the papers even though I could only grab one and hand it to her before I had to run off the train.

It was also kind of weird since I am not usually on this train at this time - I missed my appt in Rockridge so wound up taking the train up from Millbrae like normal.
Side note - coming out of BART I also saw a woman wearing the same boots I just bought on Saturday. She is thin enough that she can tuck her jeans into the tops of the boots...
