The idea of doing random acts of kindness and snapping selfies along the way came to Darius Redman, well, randomly.

The Virginia Tech offensive lineman told ESPN that he was just in line at Chipotle one day and, after talking to the man behind him, he suddenly decided, "I should buy this man's meal."

Late night Wal-Mart run! Switched it up! Purchasing someone's meal or groceries lol! #CatchMeIfYouCan pic.twitter.com/XlslaMDFBt — Darius Redman (@TheCalc_52) September 18, 2015

All Redman wanted in return was a photo. The next thing he wanted was to do it all over again. And again.

"The smile it puts on other people’s faces, they’re really thankful for me purchasing their food, so that’s enough for me to keep me going doing it," he explained.

It was even enough to get someone else doing it, too.

Subway was the move today! Purchasing someone's meal everyday for the next week! #ThisTimeItsOnDeuce #Hokies pic.twitter.com/qgSJ9OWZDY — Donovan Riley (@DeuceLRiley) September 16, 2015

After Redman pledged to do it for a full week, his Hokies teammate Donovan Riley got in on the act, too.

"Being football players, we aren’t always looked at as good people," Redman told ESPN. "So I was explaining to Donovan this is something we can do. It won’t affect us but it can make someone’s day."

But as you look through the selfies they've shared on social media since it all started, you can see by their smiles they been making their own days, too.
