After reading all of these i had to share a  story.  Bout 20 yrs ago traveled with my family to Mexico, on the trip back my pops passed a truck on the side of the road with California plates, hood open.  He decided to go back and help. my dad got the truck runnin and figured since we were headed in the same directions we should foolow each other. stopped in El Paso and got a room, the people from the broke down truck were sort of broke so my dad got them a room for the night, they were gonna sleep in their truck. next morning check the back of the truck they had left a gallon of water ther...... it was frozen solid. They ask my dad for his address so they could invite him to their daughters wedding.  to weeks later got the invite and 100 dollar check.
