aww... what a sweet story and so nice to hear "strangers" helping others in need!
I totally get the "photo first"... we are on vacation right now and on the first day, we were on the beach and a wave knocked down my DH's 87 year old grandma... my first instinct was that I must take a photo of Grandma down - how sad is that? haha But, I helped her up, helped DH rescue her shoes before they were pulled into the Pacific, got her to safe land AND THEN took a photo of her dripping wet.
