Heartwarming Tearjerker of the Day: Scott Widak has Down syndrome and is terminally ill with liver disease, and he loves to receive mail. So his nephew Sean O’Connor recently posted his P.O. Box on Reddit, to see whether anyone might be interested in sending his uncle a letter: “One of my uncle’s favorite things to do is open mail, and I thought that if he got a lot of mail it would cheer him up.”

It’s been a month since the post, and Widak, an artist, has received mail from all over the world, including the United States, Sweden, Finland, Australia, Japan, the United Kingdom, and Mexico. Redditors have sent heartfelt letters, custom artwork, art supplies, DVDs, and personal keepsakes.

“The mail that’s arrived has all been extremely positive and thoughtful,” O’Connor says. “My family and I are amazed at how so many strangers could come together for a random act of kindness.”
