A 2-year-old boy's simple gesture of love towards a pizza delivery driver has generated a ripple effect of kindness for the man and his family.

Last week, Lindsey Sheely was receiving a pizza delivery order at her home in West Warwick, Rhode Island, when her son Cohen felt compelled to run out to the driver on the porch and offer him a hug and kiss on the cheek as a thank you for their dinner.

"We thought it was so sweet and funny," Sheely later wrote on Instagram. "Then [we] realized that our doorbell might have caught the interaction on camera—and it did!!"

Sheely then posted a video of the hug to social media in hopes that it would make other people smile. To her surprise, the 20-second clip ended up on the timeline of Ryan Catterson, the delivery driver Cohen had hugged.

Catterson contacted Sheely and told her how delighted he was to find that there was a video of the exchange. Not only that, he told her that he only recently lost his 16-year-old daughter—and Cohen's hug had meant the world to him.

"After losing my daughter this past week, it touched me because it was like she was there," Catterson told WLNE. "It really just meant a lot to me."

Since the heartwarming story of the incident has been shared across social media and local news outlets, Catterson's GoFundMe campaign to raise money for his daughter's funeral expenses has surged past its original goal, garnering more than $28,000 in donations.
