I would say raising and supporting my family.
But in the spirit of things I once sat on the side of a road with a young mother and her baby after they rolled their explorer. I found the child about ten meters away from the mother and reunited them.....the child didn't make it.
I once got a call from a family looking for car help, it was very cold out, drove out the 70 miles to replace the belt only to find out it was the water pump. they had no money and everything they owned was jammed into this old Taurus wagon. I took them home for the night, feed them up right and had a customer in the town closest to the car fix em up in the morning. I can remember their two kids talking about how I lived in a mansion and must be rich.....(very much not true) humbling to think about how much we take being comfortable for granted.
of course like the rest of you guys I always stop to make sure folks are OK when stranded on the highway.
