It’s part of NPR’s my hero series where listeners call in and talk about someone who helped them out and they don’t know their name but wanna say thanks. This woman was overloading a car that’s not intended to haul that much at presumably Home Depot or similar. She has concrete being poured and was short on time so a guy offered to take the gravel in his truck. He dropped it off and left and she’s saying thanks because she never got his name etc
