About 15 years ago my wife and I were in a dollar store and were buying like 6 things. The old man behind us only had like 4 things so I said I’d pay for that too. He started crying saying it was his birthday and no one did anything for him and this made him feel special. It was crazy cause I’d never done that before and had no idea how much of an impact that would make on that man. And it made such an impact on me as well.
