Even small acts of kindness can have a major impact on someone else's life. Sometimes, these selfless acts may be so small or subtle the person doing them doesn't even realize they're helping—or even saving—someone's life in the process.
Someone asked Reddit: "What is the most selfless thing someone is unaware they did for you?"
1.) From Verticalparachute:
I was driving and hit another car. He was stopped to turn and I simply wasn't paying attention. I rear-ended his car at about 30 miles per hour. Set off my cars air bags. I managed to pull over to the side, he completed his turn. I was in shock and blundered right into the highway.
He ran out, pulled me to safety and as I'm sobbing and apologizing, he just gave me a big hug and kept telling it's ok, we're ok, cars can be fixed. He was so sweet and calm when I was a complete mess.
Found out from my co-worker a week later, the gentlemen I hit had lost his wife to cancer the week before.
