You did what you were supposed to do Bruno, that was your reason for stopping, I am totally convinced that we know these things at a subconscious level, it mirrors some of my own experiences .
One in particular was one of those...
Imagine a dark mountain road in the high country of Colorado, the wife and I are driving through to a favorite camping spot,, We spot a huge Bull at the side of the road, we both think Buffalo since there are ranches that have them around the area... I say "I want the horns" the wife totally out a character for her says "OK" normally that just would never happen.. I stop the truck and flip on the overhead light bar to see better as we turn the truck around we see a odd light off in the field pointing straight up.. We look at each other thinking X Files

It was the car, that had hit the Bull, completely totaled, with two young gals, two toddlers, and a baby,, the only one in the car not hurt was the baby,, We called for help on the CB and stopped their bleeding etc: while the Fire Dept from the next town responded..
My wife still to this day can't figure out why she said "OK" to get the horns, never happened before and has never happened again one time in 20+ years she said yes...
Sometimes you are just where you are supposed to be at the exact right time you are meant to be there, and have the right skills to save a life... The universe knocked and you answered ...
