There's a saying about people being "Iowa nice." My time in Iowa has shown me just how friendly the state's citizens can be. But this story is about more than being nice; it reaffirms my faith in humanity a little bit.

A woman named Alana Ruthann posted on Facebook about an exchange she witnessed between two men at a Walmart in Ankeny, Iowa recently. A younger man paid it forward by purchasing groceries for an elderly man wearing a veteran ball cap. He told the veteran:

Alana's post has been shared over 7,000 times and has collected hundreds of comments from people inspired by the man's kind actions. I can only hope the good deed will push others to be grateful today.
