I'll share my good deed story:
About 10 years ago I was driving to Walmart to get a prescription filled. I round a corner to find a car stopped in the road. He was in a blind spot to where if I was going any faster I would have hit him.
I stopped to ask if he needed any help. An elderly man sitting behind the wheel said he ran out of gas and was waiting for his daughter to come help. I told him he was in a bad spot so I'm going to back up about 50 yards and sit there with my flashers on so nobody will hit him, and I did.
About 10 minutes later his DD and SIL show up with gas and got him going. He drives off and his DD waves me on. As I'm driving past her she stops me to thank me. She's holding out a $100 bill insisting I take it. I proceed to tell her I don't need it and to not ruin a good deed with money. She insisted and said "you don't need it but you will meet someone that does". I reluctantly accepted her gift.
And sure enough, 10 minutes later, I'm standing in line at the pharmacy counter behind and elderly man of color of limited means. I couldn't help but overhear their conversation. He didn't have enough funds to cover all his prescriptions. They were trying to determine what he really needed at that time and what could wait until the 1st of the month.
The DD was right, I would meet someone who really needed it. I butted in, apologized for interrupting and for getting into his business and offered to help. I told them the story of how I acquired this $100, and that the daughter of the old man in the street was actually his guardian angel.
The three of us were pretty emotional at that point, especially me, so I placed the bill on the counter and said "this was meant for you" and walked out of the store.
