Can you name one thing you did to help someone today or till date?

Today I shoveled the sidewalks in my area so people could walk their dogs and get to their mailboxes. Sunday a man dropped his money while in a check out line. I was in front of him and picked it up to hand it to him. I even said..here you go, but he still acted as if I might pocket it. It's sad that trust has diminished in society.
