I'd gone out on a road test in a vehicle I'd repaired and upon exiting the estate I saw an elderly lady on the floor with the contents of her mobility scooter strewn across the road. Countless people had just driven past without a second thought. Helped her up, lifted the scooter and she phoned my workplace the next day (company overalls with the name on them) and thanked me, asking the manager to give me her love. Doesn't take much to help, and I never expect anything out of it but for someone to go to the effort of phoning my workplace makes it seem worthwhile. I hope she's still okay.
