What is the nicest thing you've ever done for someone without their knowledge?

I used to randomly make baked goods for my friends and teachers at school but, I guess they eventually found out because if I never said who it was from, they probably wouldn't've eaten it. (Can't blame them. lol)

I'm also good for leaving money around in pants pockets, cupholders in cars, jackets, and drawers to make it seem like the person just forgot they placed it there
