If EverThis happened over 30 years ago. I was going to Community College and was going to the dentist after class. I came out to the parking lot and I had a flat tire and I was going to be late to my appointment. This man shows up and changes the tire. He wasn't just out of high school and I can't say what age he was. He didn't have any books or a backpack for school. He said when I thanked him, "If you ever see my kids in the river drowning save them".
